Obstruction of justice

"The 'Highway of Tears' is a lonely seven hundred kilometre stretch of road that winds through the Coast Mountains wilderness of British Columbia. Over the last four decades nine young women have been murdered or gone missing from this remote highway. All but one were Aboriginal. To date not one case has been solved. Fuelled by frustration with the police's inability to solve any of these cries, inspired by the belief that someone somewhere knew something, and driven by his inexplicable personal commitment, ex-RCMP turned private investigator Ray Michalko embarked on a life-altering journey to unlock the secrets of these cases and, in the process, discovered as much about the crimes as he did the reasons they've gone unsolved."
