Jonas (30) comes home one night to find his fiancée, Drifa (28), dead in the bathtub. Her death is ruled suicide. Jonas finds it hard to come to terms with Drifa's death. His best friend, Thomas helps him through the grieving period and is always there for him when Jonas needs support.
Jonas works at a nursing home for the mentally disabled. The patients are a quiet bunch. One of them is Loki, an autistic mute, who is picked on by the other patients, is very attached to Jonas. One day, Jonas takes a picture of Loki. When the film comes back from the lab, Jonas is shocked to see Drifa's image in the background of Loki's photo.
He calls Thomas and shows him the picture. Thomas is shaken, but explains the phenomenon as a double exposure. Jons however begins to believe that Drifa may not be gone.
Reluctantly, Thomas joins Jonas on a visit to a psychic, who tells them that Loki is a magnet for things that have gone wrong and he is able to produce mental images on film. He warns Jonas about taking more pictures, but Jonas does not take the psychic's warning serious. He films a birthday party at the nursing home and discovers Drifa's image next to Loki's. Jonas is convinced that Drifa is trying to send him a message.
During a night shift, Thomas visits Jonas at the nursing home to watch TV. Jonas falls asleep, and when he wakes up, Thomas is gone. In the morning Jonas discovers that one of the patients has been murdered. When the police question him, he does not tell them that Thomas was with him the night before. Jonas is ordered not to leave town as he is considered a possible suspect.
Jonas films Loki at the scene of the crime and, looking at the images, sees that Thomas is the killer. He now tells the police that Thomas was at the nursing home the night of the murder, and Thomas gets arrested.
Still mystified and desperate, and feeling the presence of his dead girlfriend, Jonas continues to film in the apartment where she died. Thanks to Loki's special gift, Jonas manages to gather enough information on the tape to assume that Thomas also killed Drifa, however, the proof is missing.
When Jonas finds hard evidence that indicates it was Loki after all who killed the other patient, he is faced with a dilemma. He is still convinced that Thomas killed Drifa. Should he tell the police that the right man is in jail, but for the wrong crime?
