Based on Akimi Yoshida's josei manga 'Umimachi Diary', 'Our Little Sister' is a women-centred, Japanese chick-flick. A story that revolves around three sisters who live in their grandmother's home and the arrival of their thirteen-year-old half sister. Adult sisters Sachi (the serious one), Yoshino (the sexy partying one) and Chika (the comedy relief one), abandoned by their father when they were just small children, live in the large, old house turned over to them by their mother when she too abandoned them as teenagers. With Haruka Ayase, Masami Nagasawa, Kaho, Suzu Hirose. Directed by Hirokazu Koreeda. "Our Little Sister" provides us with an intriguing family dynamic that might seem like Science Fiction to some while relating immensely and accurately with others.
