This documentary unpeels the complex life of Diane, an aspiring actress and mother, and the shockwaves that a series of impulsive actions unleash on her children, husband and community.With this groundbreaking new feature that seamlessly blends past and present, the real and the imagined, Polley's characteristically unflinching yet compassionate gaze delivers a level of depth and emotion only hinted at by her acclaimed earlier directorial works, Away From Her and Take This Waltz.Making this film all the more memorable is the revelation that the mother depicted and family in question is Polley's own.
