In a high-security psychiatric clinic sits Thomas Quick, Sweden's most notorious serial killer. A misfit loner who openly confessed to a range of crimes, including rape, murder and cannibalism, his story has shocked and haunted the Swedish nation for more than 20 years. However, new evidence - including testimony from the man himself - has taken this terrifying story in an even more disturbing direction. With full access to Quick, Brian Hill's film is a chilling documentary that uncovers a dark tale of murder and lies.
