The recipient of the Jury Prize at the 66th Cannes Film Festival, Hirokazu Koreeda's heartfelt drama tells the tale of Ryota (Masaharu Fukuyama), a success-driven father who learns that the son he has raised for six years is not his own due to a clerical error at the hospital where the child was born. Faced with the decision of raising his biological son or the one he has fathered since birth, Ryota begins questioning everything he has ever known about being a father.
