When her parents split and her father Kenichi moves out of their family home, Renko, a bright and energetic 6th grade girl, is left alone with her mother, Nazuna, in Kyoto. As Nazuna sets out new rules for their life together, Renko makes plans of her own—hiding the divorce papers, plotting a siege at home, and even arranging a short trip to Lake Biwa where they once vacationed as a family—seeing to it that any changes happening in her family happen on her terms. Adapted from Hiko Tanaka's 1988 novel of the same name, this coming of age film is a breathtaking masterpiece begging for rediscovery from one of Japan's undersung auteurs.
