What is real? What is true? What do we remember? Using home movies, photographs, and interviews, Sarah Polley delves into the life of her mother, a creative yet secretive woman. But while she is talking to her relatives, her interest lies in the bigger picture of what families hold onto as truth.

This astounding documentary digs into a family history to portray the director’s mother through a patchwork of stories and materials. By disclosing her filmmaking process, Sarah Polley audaciously shows that the past we construct can be warped through the lens of both our memories and cinema.
