Fallen

Detective John Hobbes visits the condemned serial killer Edgar Reese on death row. Reese appears unnervingly cheerful, utters what sounds like gibberish in Syrian Aramaic, and mocks the witnesses as he is executed. He finishes by singing Time Is on My Side.

Shortly after Reese's death, a series of killings mirrors the killer's methods. Hobbes and his partner Jonesy suspect a copycat is at work and start tracing the similarities. The police unit begins a nationwide look for the pattern.

Hobbes follows the clues to Gretta Milano, whose late father, a detective, killed himself after being accused of occult-related killings. He asks her for information that could link the current murders to an old case. The conversation hints at deeper, unsettling connections.

In the abandoned Milano family cabin, Hobbes discovers books about demonic possession. The name Azazel is hidden beneath layers of paint in the basement, signaling a possible link to the new killings. The find deepens the mystery and hints at supernatural forces.

Gretta initially urges Hobbes to abandon the investigation. Later she explains that Azazel is a fallen angel who can possess humans by touch, making him difficult to identify. She warns that the demon will try to ruin Hobbes.

Hobbes notices people around him singing Time Is on My Side, realizing the demon is moving from host to host. The taunting shifts through various witnesses, including members of the police. The sense of paranoia grows as the line between ally and suspect blurs.

Azazel temporarily possesses Hobbes' nephew Sam and uses him to attack his brother Art. The family becomes directly endangered as the possession escalates. Hobbes grapples with the terrifying reality of the demon inhabiting close relatives.

Azazel engineers a confrontation that forces Hobbes to shoot a possessed schoolteacher in front of witnesses. The act immediately frames Hobbes in public suspicion and threatens the credibility of the investigation. The incident escalates the demon's influence over ordinary life.

Witnesses, influenced by Azazel's manipulation, implicate Hobbes in the schoolteacher's death. The mounting evidence drives the investigation toward a man who seems haunted by the demon. Hobbes fights to clear his name while the demon tightens its grip.

Azazel murders Art and marks Sam, prompting Hobbes to hide his nephew with Gretta. The family is thrust deeper into danger as the demon closes in. The threat becomes personal and immediate.

Gretta explains that if expelled from a host body, Azazel can only survive for the length of a single breath. They plan to lure Azazel to the Milano cabin where they might trap him. The plan hinges on depriving the demon of new hosts.

Hobbes lures Azazel to the Milano cabin as Jonesy and Lieutenant Stanton arrive. Jonesy, now possessed, kills Stanton. Hobbes shoots himself in a bid to force the demon into his own body, and poisons himself to ensure the demon dies if it enters him.

Azazel briefly inhabits Hobbes but succumbs to the poison, and appears to be defeated. Yet a cat emerges from beneath the cabin, suggesting the demon has survived by transferring to an animal. The closing credits feature Sympathy for the Devil.
