A loner from an early age, Thomas Quick went on to become Sweden's most notorious serial killer, openly confessing to the gruesome murders of more than 30 people. Held for decades in a psychiatric institute, Quick's confessions emerged after years working with a group of touchy feely therapists, convinced that the recovery of memories would cure patients of their criminality. In a country with a low crime rate, the nation watched with horror as Quick's confessions mounted, accounting for many of the country's unsolved murders. With testimonials from a range of people whose lives have been dominated by this story - including Quick himself - and dramatic reenactment, Brian Hill weaves a stylish noir thriller that works a treat on the big screen. What appears at first to be a tale of unimaginable evil evolves into something much more layered as Hill digs deep into the motivations behind those working closely with Quick.
