Near Montreal, a husband comes home from work and finds his wife bound, gagged and shot in the head. There is no evidence of sexual assault or theft and police are left without a lead to go on. Some years later, police are called out to a crime scene very similar to the scene four years earlier, but this time they find that the killer has stolen the victim's bankcard. They trace the card to a convenience store and by ingeniously matching the security camera to the bank records detectives acquire an image of their prime suspect. Police quickly locate and arrest the man who promptly admits to both murders as well as the murder of a woman gone missing 7 years earlier.
