Dan (Don McKellar) and Linda (Tracy Wright) are two ex-revolutionaries, now living underground and off the grid. Bound together by misdeeds of the past, the once passionate pair have become ambivalent about their political beliefs and feelings for each other. Dan and Linda's lives are turned upside down when they meet an enigmatic young radical named Susan (Nadia Litz) whose involvement in revolutionary activities could threaten them. As it turns out, Susan's guerilla antics are nothing compared to what she eventually learns about the past Dan and Linda have been hiding from. Monkey Warfare is a film about history, bicycles, love and revolution.
