Japanese director Hirokazu Koreeda's touching film follows the empty lives of 12-year-old Akira (Yûya Yagira) and his three younger siblings (Ayu Kitaura, Hiei Kimura and Momoko Shimizu) after their mother abandons them in a tiny Tokyo apartment. Pragmatic, determined and wise beyond his years, Akira manages the household as best he can -- but eventually the money runs out, and the children must find new ways to survive. Based on a true story.
