All over the world, people suddenly begin panicking as they start to see everyone around them as demonic monsters and end up killing innocents before members of the Justice League stop them. Deliberating about this strange outbreak, most of the League’s members come to the conclusion that magic must be involved in this. Despite his past experiences with magic, Batman expresses his skepticism and walks out; but as he returns to Wayne Manor to rest, he finds the word “Constantine” written all over the walls.
In a flashback, occultist John Constantine and Jason Blood– engaged the Demons Three in a poker game in Las Vegas for high-end stakes, even offering his home, the House of Mystery, as his part of the pool in exchange for a box of artifacts, including one called the Dreamstone. However, both parties cheated at the game, and when Constantine exposed the Demons’ trickery, they attacked him. Constantine unleashed Jason’s alter ego, the demon Etrigan, who defeated the Demons Three, but not before they swore revenge on him.
Batman visits Zatanna after one of her performances and begins to ask about Constantine. Deadman possesses Batman and tells Zatanna she needs to see John. Zatanna brings Batman to Constantine. The trio narrowly manages to get inside John’s house in time where they are joined by Black Orchid. The group gathers to share information, and after a quick discussion and some argument between John and Zatanna, form a team to investigate the cause and reason for these supernatural occurrences.
The heroes visit a friend of Constantine and Zatanna’s named Ritchie Simpson, but outside the house, they find shroud spirits of Death waiting to collect Ritchie’s soul upon his upcoming demise. The team is granted entry by Simpson, who is suffering from magical cancer and resentful of Constantine for abandoning him to his fate but loans them the Ashanti Key. Constantine and Zatanna look through a man’s memories for the cause of his frenzy and discover that he was possessed. Batman, Deadman, Constantine, and Zatanna narrowly manage to escape from a conjured beast as the creature consumes its victim, and Zatanna proceeds to destroy the monster.
Returning to Ritchie’s home to identify the ring from the man’s memory, the team finds him about to die with Blood nearby. Batman revives Ritchie with an adrenaline shot to the chest, but he quickly falls into a coma. After being brought to the House of Mystery for interrogation, Blood tells the team that he did not attempt to hurt Ritchie, but was looking for a way to the House of Mystery to find the Dreamstone; created by a sinister magician naming himself Destiny. Ritchie awakens and names Felix Faust as his assailant before falling back asleep.
The group locates Faust’s Observatory with help from Swamp Thing. When they infiltrate Faust’s lair, the wizard battles the team, but is ultimately defeated by Zatanna; however, Faust is found to have no involvement in hurting Ritchie. Ritchie awakens and is revealed to have the other piece of the Dreamstone; using it to keep his cancer in remission, but then he is seemingly killed when the Dreamstone brings Destiny back to life. Destiny declares himself a god, destroys the House and departs to sink the United States into chaos; Zatanna saves the group but passes out from the exertion. The Justice League tries to fight Destiny, but he makes them perceive each other as demonic threats. Etrigan attacks Destiny but is separated back into Jason Blood and Etrigan. Constantine summons Swamp Thing, who agrees to fight Destiny, while Batman and the recovered Zatanna disable the Justice League.

Constantine tricks Destiny into bringing him and Deadman within his protective shield, allowing Deadman to wound Destiny, before Constantine, Batman, and Blood destroys the Dreamstone and Destiny’s body, leaving Ritchie, whose soul is dragged to Hell by the shroud spirits. Right afterward, Blood succumbs to his mortal wound from centuries before. Zatanna, Constantine and Etrigan bury Blood’s body near the place of his old village before Etrigan leaves for parts unknown. Zatanna agrees to join the Justice League, while Constantine declines (knowing Batman won’t approve if he did). The two return to the now-rebuilt House of Mystery, taking a first tentative step to restoring their fractured relationship, and Deadman likewise joins the restored Black Orchid as her soulmate.
