Summer, Quebec City. Following the brutal murder of a young woman, police suspicion rests on one of her close friends, Francois, a student of political science. Meanwhile, a coroner conducts the gruelling autopsy. Based on an uncanny series of interwoven true stories, Polygraph - by Robert Lepage and Marie Brassard - is a play noir: part metaphysical thriller, part murder mystery and part love story, played out in a riveting series of overlapping and shifting perspectives.
