Based on the New York Times bestselling young adult fantasy book series The Mortal Instruments by Cassandra Clare, follows 18 year-old Clary Fray, who finds out on her birthday that she is not who she thinks she is, but rather comes from a long line of Shadowhunters — human-angel hybrids who hunt down demons. When her mother Jocelyn is kidnapped, Clary is thrown into the world of demon hunting with mysterious Shadowhunter Jace and her best friend Simon. Now living among faeries, warlocks, vampires and werewolves, Clary begins a journey of self-discovery as she learns more about her past and what her future may hold.


Season 1

Episodes Original Air Date Description
The Mortal Cup; S01E01 January 12, 2016 On Clary Fray's eighteenth birthday, her mother, Jocelyn, is kidnapped. Soon after, Clary discovers that her mother belongs to a supernatural group called Shadowhunters, a half-angel/half-human race tasked to protect the Downworld (faeries, werewolves, vampires, and warlocks) from demons. Clary learns she also belongs to this race, after being saved by a fellow Shadowhunter named Jace – who then introduces her to his adoptive siblings Alec and Isabelle. Clary overhears her mother's friend, Luke, claim that he cares nothing about her or her mother. Clary is at a crossroads not knowing who to trust – her best friend Simon or the Shadowhunters – to help save Jocelyn from Valentine, a dangerous rogue Shadowhunter.
The Descent into Hell Isn't Easy; S01E02 January 19, 2016 The Circle has returned, as has Valentine. With the Shadowhunters searching for the Mortal Cup, the Institute is on alert. After Hodge tells Clary that Jocelyn was once a Circle member, they realize Clary's significance in the cause. Jace realizes Clary's memories are the only way to find Jocelyn and the Cup. Unfortunately, without her memories they are unable to help her or the Shadowhunter team. Thus Jace, Isabelle and a reluctant Alec take Clary and Simon to visit the powerful Silent Brothers in the City of Bones, where Clary fails to retrieve any memories but finds out her biological father is Valentine himself. Meanwhile, Luke is worried about Clary's whereabouts, while Simon comes to terms with Clary's new life and gets kidnapped by vampires.
Dead Man's Party; S01E03 January 26, 2016 The Shadowhunters plan to rescue Simon, who has been taken captive by vampires in exchange for the Mortal Cup. Jace, Isabelle, Alec and Clary locate Simon's whereabouts to the Hotel Dumort, where he is being held by Camille Belcourt, Raphael Santiago and the rest of Camille's outfit. Alec and Jace have a dispute over Clary and her loyalty, since her father is their enemy. Isabelle visits Meliorn, her Seelie lover, in order to extract information about the Hotel Dumort, so the group can get into the building unnoticed. The Shadowhunters retrieve Simon and he is reunited with Clary, but he appears to be turning into a vampire after drinking Camille's blood.
Raising Hell; S01E04 February 2, 2016 Simon quarrels with Jace and leaves the Institute. The Shadowhunters lure warlock Magnus Bane out of hiding with a prized necklace, in order to gain his help in retrieving Clary's memories. Magnus informs them that he fed the memories to a memory demon for safekeeping. The Shadowhunters track Magnus to his lair, where the Circle has attacked. Magnus transports the group to his loft, where they summon the demon. Alec's personal insecurities about his feelings for Jace disrupt the ritual when they are each asked to relinquish a beloved memory, forcing Clary to kill the demon before recovering any memories. Meanwhile, Simon is plagued with visions of Camille, and ends up returning to the Hotel Dumort.
Moo Su To Go; S01E05 February 9, 2016 The Lightwood family matriarch, Maryse, arrives at the Institute with a Seelie intel mission for Isabelle and Jace. Alec is ordered to watch over Clary, but she escapes the Institute for her old apartment to locate her mother's secret box – that once belonged to a "Jonathan Clark". Clary and Simon are subsequently kidnapped by werewolves while searching the apartment, to Alec's chagrin. Clary is interrogated about the location of the Mortal Cup, and the alpha werewolf threatens to kill Simon if she does not reveal the information. Jace, Isabelle and Alec then head to rescue the two, after Simon calls for help. The Shadowhunters are assisted in their escape by an unlikely ally – werewolf Luke, who defeats his alpha and assumes the title.
Of Men and Angel; S01E06 February 16,2016 Clary, Jace and Simon take a mortally wounded Luke to Magnus for help. At Luke's insistence, Magnus informs Clary of the Circle's past and her mother's involvement with the group. Meanwhile, Robert Lightwood arrives at the Institute, and he and Maryse task Isabelle with mending the Seelies' broken ties with the Clave and restoring the family name. When Isabelle informs Alec that their parents plan to marry him off, he angrily leaves the Institute for Magnus' loft. There, he, Magnus and the others save Luke's life with magic. Luke informs Clary that she had a brother, Jonathan Christopher, who died in a fire caused by Valentine. Clary then discovers one of her powers, making her realize she knows the whereabouts of Mortal Cup.
Major Arcana; S01E07 February 23, 2016 Clary reveals that the Cup is hidden in a tarot card that Luke took for safekeeping. When Luke goes to retrieve it from his desk at the precinct, he is detained by internal affairs officers due to demonic murders whose real killer was Valentine. While being questioned about his part in the demonic murders, Luke's boss is killed by a shapeshifter. Clary, Jace, Isabelle and Alec enact a plan to obtain the Cup, but are tracked by demons. When a demon posing as Jace attempts to take the Cup from Clary, she kills it. Afterward, Clary and the real Jace share a kiss at the Institute. Meanwhile, Simon's odd behavior worries Maureen and his family, who fear he is on drugs. He returns to the Hotel Dumort looking for answers and is met by Camille.
Bad Blood; S01E08 March 1, 2016 Raphael arrives at the Institute with Simon, who has been attacked and killed by Camille. He informs Clary that, unless Simon is staked or turned before sunset, his soul will be trapped for eternity. An envoy from the Clave, Lydia Branwell, arrives to temporarily take over the Institute. Valentine sends a Forsaken to attack the werewolf pack, but Luke kills it. While retrieving the corpse from Luke, Lydia inadvertently reveals to Alec that his parents are ex-Circle members. Isabelle performs a pathology test on the Forsaken and finds that it has angel blood. Alec decides to restore his family's honor (due to the current situation) by proposing to Lydia. Later, another Forsaken attacks Hodge and Alec at the Institute, but they eventually defeat it. Clary decides to bury Simon in order for him to turn into a vampire, but he emerges thinking of himself as a monster.
Rise Up; S01E09 March 8, 2016 Following the Forsaken attack, the Institute is on high alert. Lydia arrests Meliorn for supposedly leaking Shadowhunter information to Valentine. During his interrogation, Meliorn lets slip that Clary is in possession of the Mortal Cup. Jace, Isabelle and Clary decide to take matters into their own hands to prevent the Cup from reaching the Clave. With the help of Magnus, the three Shadowhunters sneak the Cup out of the Institute. Later, Isabelle, Clary, Jace, Simon, Luke and Raphael team up to rescue Meliorn from his impending torture in the City of Bones. Afterward, Meliorn informs Clary that he can help find her father.

This World Inverted; S01E10 March 15, 2016 Meliorn takes Clary and Jace to the Seelie realm where he reveals a portal to an alternate dimension. He tells Clary that if she locates another portal within this dimension, she will be transported to her father. However, when Clary arrives, she finds that Shadowhunters have ceased to exist in this peaceful world and may assimilate to Clary from that dimension. Jace and Meliorn protect the entrance to the dimension from demons, but when one slips through, Jace ventures in to stop it. With the help of Magnus, Clary finds the portal at the Institute, and she and Jace step through it. When they arrive at Valentine's hideout, they discover Jace's father, Michael Wayland, assumed to be dead, is being held captive there.

Blood Calls to Blood; S01E11 March 22, 2016 Clary, Jace and Michael Wayland head to Luke's for help. While there, Michael discloses the location of Valentine's new hideout – an abandoned hospital in Long Island. Jace, Michael, Luke and Clary go to rescue a still-unconscious Jocelyn, but are surrounded by demons. Michael takes the Mortal Cup to command the demons, but then reveals himself to be Valentine in disguise. Clary subsequently reveals that Valentine is holding a duplicate Cup. Before fleeing through a portal, he informs Clary and Jace that they are siblings. Meanwhile, Isabelle's trial begins, with Magnus as her defense attorney. During questioning, Lydia states that the trial is nonsense and withdraws the charges, but Inquisitor Herondale states that Isabelle will still be banished from Shadowhunter society if the Clave does not receive the Cup within 24 hours. Jace and Clary arrive back at the Institute with the Cup, dropping the charges against Isabelle.
Malec; S01E12 March 29, 2016 Jace is conflicted with his feelings for his sister Clary, and Alec is conflicted with his feelings for Magnus in the lead up to his wedding. Isabelle throws her brother a bachelor party, where Alec and Jace mend their broken bond. Meanwhile, Jace, Clary and Magnus visit Ragnor Fell for help on waking Jocelyn, but a demon kills Ragnor after he mentions that the Book of the White holds the antidote. During the wedding ceremony, Magnus arrives (whom Isabelle had secretly invited), making Alec realize he cannot go through with the marriage. After apologizing to an understanding Lydia, he approaches Magnus and kisses him in front of the guests. Later, Maryse expresses her disappointment in Alec, though Robert offers support. Magnus finds that the Book of the White is in Camille's possession. Packing up to head back to Idris, Lydia retrieves the Cup from a safe but is attacked by Hodge. It is revealed that Hodge stole the Cup for Valentine in order to be freed from his binding curse.
Morning Star;S01E13 April 5, 2016 The Shadowhunters find out that Hodge has fled with the Mortal Cup. Now in possession of the Cup, Valentine begins creating his Shadowhunter army. Jace and Alec hunt down Hodge with Luke's help. Jace finds him and the two battle, with Jace chopping off Hodge's hand. Jace then goes after Valentine on his own. Meanwhile, Clary, Isabelle and Simon visit the Hotel Dumort to ask Camille about the Book of the White. The three eventually break her out from her prison (as a punishment to turn Simon into a vampire) so she can take them to it. Clary, Simon, Isabelle and Camille arrive at Magnus' loft, where the warlock drafts a contract stating Simon asked to be turned into a vampire, a requirement of Camille's in exchange for her help. The group then heads to Camille's apartment, where they find the Book but are ambushed by the Circle. Jace arrives to fight Valentine, but ultimately joins him in order to protect his friends and save their lives. Back at the Institute, the devastated group wake Jocelyn, who reunites with her daughter and Luke.

Motto:Descensus facilis Averno est,
"The descent into Hell is easy"

Shadowhunters, also known as Nephilim, are a race of beings who are humans born with angel blood. They have fought the demons that threaten the world and have created their own culture and civilization within human society over the years, at the same time keeping the Shadow World a secret from the mundane world while protecting both.
Their angelic blood endows them with special abilities that allow them to achieve feats beyond what's humanly possible through the application of angelic runes. They are based in Idris but are worldwide.
Werewolves, also known as Lycanthropes, are a species of Downworlders. Their demonic infection gives them the ability to Turn into powerful wolves and gain inhuman strength and enhanced capabilities.
Werewolves in their lupine and human forms possess supernatural strength, grace, speed, and reflexes, with strong claws and canines. They also have the same unnaturally accelerated healing abilities as most other Downworlders. Their distinguishing feature are their eyes which change to a particular color for each individual werewolf at will.
An alpha werewolf has poison in his/her bite. This poison is fatal and needs serious intervention to be survivable. Known side effects of the poison are random transformation of the werewolf and hallucinations.
New werewolves are created when an existing werewolf bites or scratches a human. However, not all attacks may cause a human to Turn.
Newly-made werewolves need to learn to gain control of his or her transformation. When werewolves first Turn, any stress or emotion, especially grief, can set them off, making them lose control of themselves and their consciousness to happenings and people around them.
Many werewolves, like vampires, belong to a group: in their case, a pack. Each werewolf pack is lead by an alpha wolf. Any werewolf that kills the pack leader will subsequently gain control of the pack. Werewolves follow the long held tradition of being mortal enemies of vampires.
Warlocks are an immortal race of Downworlder offsprings of demons and mundanes.
Warlocks are born from demons and humans. They are immortal beings who, at one point in their lives, stop aging.
Warlocks are capable of performing magic and casting spells in demonic languages. Most are also versed in making potions.
A universal trait among them are their warlock or demon marks, a part of their body that is strange or unique that identifies them.
Additionally, warlocks are unable to have children. Within certain districts, there is one warlock who is proclaimed the "High Warlock"—they are recognized by other Shadow World denizens as a powerful figure and a sort of leader of the local warlocks.
A human who has consumed enough vampire blood, known as a fledgling, will not abruptly Turn into a vampire. To be reborn, the human must first die a mortal death, during which the undead body will enter into a state of transition. They must then be buried, during which they will reanimate while in the ground, and then must make their way out of their own grave to be truly 'reborn'. They must then feed on an exceptional amount of fresh human blood within the next 24 hours to complete the transition, or else they will fade and die.
Because of this, a killed fledgling should have someone familiar with the process to support the fledgling and ensure a smooth transition, specifically by being present for the vampire's rising, to ensure that the fledgling would successfully rise of the grave, and supply him or her with blood and take him or her to a safe place to recover.
Their immortality does not make them immune to other forms of death.
Vampires are extremely vulnerable to the sun as well as fire. A ray of sunlight will cause blisters and burns on a vampire's skin, but full exposure to the sun or being exposed fully to unblocked sunshine will cause them to explode. A known exception to this are Daylighters, who are immune to forces that would typically destroy his kind, such as the sun and the Soul-Sword.
As stated by tradition, the use of a wooden stake to pierce through a vampire's heart will slay them instantly.
The dirt of the grave where a vampire was buried holds special properties for that vampire; thus, it is often well-protected. The vampire can tell if the grave has been disturbed. Vampires may use this to communicate simple messages, even without the other's presence—for instance, breaking a container of a vampire's grave dirt could be used to alert and summon that particular vampire.
Seelies are beings who are half-angel and half-demon.
Seelies are also known as faeries, or the Fair Folk. Pixies, nixies, and elves are also considered Seelies. They cannot lie, though they use evasive and distraction tactics to avoid directly answering questions they do not want to. They are an extremely manipulative, cunning, and mischievous race of Downworlders, their angel and demon blood attributing to both their beauty and malevolence.
Angels are winged celestial beings which have fought against the demon legion for eons. According to legend, it is an angel, specifically Angel Raziel, who created the Nephilim with the Mortal Cup and his blood.
Demons are predatory creatures that travel between worlds from their native dimension of Hell; typically disrupting and destroying life around them. Their exact origin and purpose is unclear, although it is known that demons have existed for eons and have been fought by angels and Shadowhunters for centuries or more.
Demons - depending on their breed and rank - range in intelligence from basely animalistic to so sentient they can easily pass as human; although all tend to be bestial, even savage, in their temperament.
Demons can also be used as weapons or servants by powerful people who could be capable of controlling them, such as warlocks - who are themselves half demon.
Demons Demons come in a large variety of species and forms with almost seemingly infinite numbers. Most are easily recognizable as they almost always take on monstrous appearances on Earth, unless they are shapeshifters. Their blood, referred to as ichor, is infused with dark energies and is both black and viscous. While ichor is not generally dangerous, it is somewhat toxic and poisonous, and some are acidic and can burn what it touches.
To human eyes, their disappearance can take many forms, depending on the type of demon. Some explode or burst into dust, some fade from view, and some crumple into themselves. Some leave behind ashes or smoke, depending on the manner of its death.
The most immediate weakness of demons is their vulnerability to angelic power. However, like the Downworlders they brought into being, they cannot easily, or permanently, be harmed by normal earthly weapons, so most Shadowhunter weapons are marked with runes to strengthen them against demons.
Possession of the Mortal Cup can grant control over demons.
Mundanes, also called mundies by some, are regular humans who are oblivious to the existence of Shadowhunters, Downworlders, demons, and the rest of the Shadow World. When Nephilim, demons, or warlocks put up glamours, it is so that mundanes cannot see them. The secrecy of the Shadow World from mundanes is of utmost importance to most of its residents.
Downworlders are supernatural beings and hybrid creatures who inhabit the Shadow World. "Downworlder" is the widely used term to refer to beings that are said to be part human and part demon. The Downworlders are werewolves, vampires, warlocks, and Seelies.
Though the Shadowhunters and Downworlders do not exactly have harmonious relationship, they are civil and have a longstanding alliance and a treaty—the Accords—in an effort to keep peace in general.
