When Rob Roberge learns that he's likely to have developed a progressive memory-eroding disease from years of hard living and frequent concussions, he’s terrified by the prospect of becoming a walking shadow. In a desperate attempt to preserve his identity, he sets out to (somewhat faithfully) record the most formative moments of his life. But the process of trying to remember his past only exposes just how fragile the stories that lay at the heart of our self-conception really are. As LIAR twists and turns through Roberge’s life, it turns the familiar story of sex, drugs and rock ‘n’ roll on its head.
