Demonic (2015) – Full Plot Summary & Ending Explained

Read the complete plot breakdown of Demonic (2015), including all key story events, major twists, and the ending explained in detail. Discover what really happened—and what it all means.

A violent slaughter occurs in an abandoned house in Louisiana where three college students are found dead. Detective Mark Lewis, Frank Grillo, arrives to assess the scene and calls for reinforcements. A shaken survivor, John, Dustin Milligan, is found and brought into questioning, while an ambulance arrives with the psychologist Dr. Elizabeth Klein, Maria Bello.

She talks to John, who says a séance in the house drew the attention of many spirits, including one he identifies as his mother, and that two group members—the pregnant girlfriend, Michelle, Cody H. Carolin, and her ex-boyfriend Bryan, [Scott Mechlowicz](/actor/scott-mechlowicz—are missing.

The story unfolds through two interlaced plots: one follows the interrogation of John by Dr. Klein and the police as they examine videotapes found in the house, and the other replays the actual events (often filmed by a camera) that John and the five other visitors experienced, featuring escalating paranormal phenomena.

Bryan is later found alive but runs away from the police, ending up cornered in a store. John hears the news on the police radio and, in a fit of rage, grabs a radio, shouting at Bryan to tell him where Michelle is. Bryan begins to act strangely while John nearly has a heart attack. Elizabeth screams for Mark to stop Bryan before he kills John, and Mark promptly shoots Bryan dead.

Mark returns to the house and discovers a secret area where he finds Michelle. As the paramedics roll her on the stretcher, Elizabeth discovers that John killed everybody at the same time that Detective Mark finds John’s lifeless body hanging.

The twist reveals that the “John” Elizabeth interrogated was a demon, who, as he starts to choke her, explains that the seal in the living room binds him to the house; John’s mother was meant to be the vessel of his escape, possessing John and killing everyone, so he can cross the seal and set himself free. The lights flicker, and when Mark bursts through the door, the demon vanishes just as Michelle is wheeled out of the house.

The film ends with Michelle in the ambulance, and a sinister figure moving in her belly, hinting at the demon’s attempt to escape into a new host.
