The 2007 murder of British exchange student Meredith Kercher in Perugia, Italy has become a case study in the vagaries of crime and punishment. Seattle native Amanda Knox and her boyfriend Raffaele Sollecito were convicted and - after four years in prison - acquitted for Kercher's murder, though just what happened on that November night remains shrouded in mystery.

This gripping, atmospheric documentary from directors Rod Blackhurst and Brian McGinn revisits the story with unprecedented access to its key players and poses troubling questions as to why both the legal system and outside observers got so much wrong about the case.
