One cold February morning in the dark stairwell of a Toronto apartment building, a security guard makes a grotesque discovery: the dead body of a Filipina nanny. It's clear she's been savagely murdered and raped. Police analyze the list of potential suspects - the boyfriend, the employer, serial offenders in the community.

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.
