We all make mistakes. We lock our faults in the closet of our past, and try to carry on. For a while, we delude ourselves that Life has forgotten our debt, but the moment when She brings us the bill always comes. And seldom does she cancel the interest... United States. A young woman learns that two girls, whom she'd met at a summer camp many years before, have been brutally murdered. Although it seems to be a tragic coincidence, she starts to fear for herself and goes to the police. The handsome detective who listens to her finds her theory very weak; nevertheless, he decides to check it out: the sexual background of the story might justify her fear. The events of the following days link past and present, entwining their lives with the killer's in an unpredictable way.
