72 Hours: True Crime

A young couple hit the road, hitchhiking their way across North America. They're free spirits keen to explore life and the world. When the young woman stops phoning home, her father becomes alarmed. But police dismiss the case as normal behaviour for a pair of young travelers.

A Girl Guide leader is found dead in her home on the floor of her bedroom. As there is no obvious cause of death, police are suspicious. When an autopsy reveals a small bullet lodged within the victim's brain with an entry wound through the left eye, detectives learn they're investigating a murder.

Stuck at home and tired of the boredom, a retiree takes a job at a 24-hour convenience store. On her third night at work a customer finds her on the floor behind the register, face down in a pool of blood. Detectives determine that her last customer was also her killer. Only two witnesses saw that customer. And in a town where everyone seems to know everyone else - he was a stranger. Find the stranger, find the killer. But how do you find a man who's defining characteristic is that no one knows who he is?
