In a small town in the north of England, a stranger trespasses into a mortuary. Night after night he appears but the Coroner and his staff fail to catch him in the act. The only thing he can deduce from these 'visits' is that the trespasser is fascinated by the corpse of a young woman. When a strikingly similar incident occurs in Germany, Henry, a medical instructor who is very close to these events decides to investigate on his own.
