Oscar-nominated writer/director Sarah Polley investigates the truth about her family history in this deeply personal and beautifully crafted documentary. At the heart of the story is Polley's mother, Diane, who died when Polley was 11, leaving behind a trail of unanswered questions. Through candid, often contradictory interviews with her family and others who loved Diane, Polley reveals how each person holds onto their own version of the past. Woven amongst their recollections are nostalgia-tinged glimpses of Diane: a bon vivant who lived life to the fullest. The film is both playful and poignant as it explores the elusive nature of memory and truth. Polley unravels the paradoxes to reveal the essence of family: always complicated, warmly messy and fiercely loving.
