Following the Mortal War, Magnus Bane and Alec Lightwood are on a vacation to Paris. Magnus reveals to his lover, Alec that he had been to Paris many times over his Immortal life. Magnus and Alec discover a friend of Magnus named Johnny Rook who questions him about the Crimson Hand a cult that Magnus Bane remembers. Johnny explains that Crimson Hand is responsible for disappearances of several Downworlders. Tessa Gray Interrupts them and drops in on them in their hotel room and says the the world believes Magnus Bane is the Crimson Hand's leader and founder. Magnus and Alec decide to seek out the Crimson Hand to clear Magnus's name.

While exploring the Shadow Market, Magnus discovers a password to get into the Crimson Hand's headquarters and Venice. He realizes that his father, Asmodeus, is involved. While on a train to Venice, Alec and Magnus come into contact with demons and meet a warlock named Shinyun Jung who claims to be a rogue follower of the Crimson Hand hunting them for revenge. In Venice, the team finds the Crimson Hand's abandoned headquarters that's used for parties by Downworlders. Magnus finds a sacred book called the Red Scrolls of Magic which he recognizes although his memories are foggy. Magnus, Alec and Shinyun escape while the Downwolder's clash over politics.

Reading the Red Scrolls of Magic, Magnus Bane discovers clues leading them to the City of Rome. While investigating, Shinyun and Magnus investigate a bathhouse run by vampires where Shinyun seduces Magnus and slips his drink which leaves him vulnerable. She leads him into a trap by the Crimson Hand and they take Magnus Bane hostage. Shinyun reveals that she is the Crimson Hand's true leader. The cult prepares to sacrifice Magnus Bane to summon his father Asmodeus who orchestrated the cult's actions. Asmodeus taunts Magnus Bane by triggering his foggy memories of founding the cult. Magnus had originally started it as a Robin Hood-minded parody religion and Asmodeus had manipulated it's first generation of followers to keep it going.

Shinyun begins a dark ritual to summon Asmodeus. Asmodeus begins to take physical form on Earth but reveals he plans to use Shinyun as a sacrifice instead of his son. Alec Lightwood teams up with Aline and Helen two Shadowhunters from the Los Angeles Institute and they break into the cult's headquarters and battle demons. Alec finds Magnus Bane prepared to be sacrificed and saves him by sabotaging the ritual, defeating the non-corporal form of Asmodeus and defeats Shinyun. The Shadowhunters join in the battle and apprehend the demon worshipping cultists. Magnus Bane choses the spare Shinyun and she takes advantage of the situation to escape.

In a post-credits scene, Shinyun is seen torturing Ragnor Fell and claims she has a plan that involves The Eldest Curses.
