Successful building contractor Ulrik Hansson (Ralph Carlsson) returns to his stressful life after coming back from a fishing vacation with his family. Everything seems back to normal until Ulrik wakes up the next morning to find his wife and two children missing and his sheets covered in blood. He contacts the police and informs them he was passed out due to the combination of wine and prescribed Hypnotic. Fearing he may have been sleepwalking, Ulrik straps a video camera to himself to record his nocturnal activities and figure out what happened to his family. Meanwhile, Inspector Levin (Anders Palm) begins to suspect Ulrik may not be telling the entire truth.
