In 1942, a 10-year-old boy named Timmy is chastised by his mother for playing with a jigsaw puzzle of a nude woman. After she orders him to dispose of the puzzle, he returns with an axe, murders her, then dismembers her body with a hacksaw. When the police arrive, Timmy hides inside a closet and pretends to be a witness to the crime. The police believe Timmy's story and he is sent to live with his aunt. Forty years later, a black-clad figure opens a box containing the bloodied clothing and a photograph of Timmy's mother. He also unboxes the bloodied jigsaw puzzle and starts to put it together.
