Through the story of his own family, where the absence of a father is passed down from one generation to the next, the filmmaker seeks answers to a question that haunts him: how does a child grow up without a father? And how does a father grow up without his child? The answers emerge through an unusual journey, a memory game where one moves from square to square, from railway landscapes to public gardens, from a Maginot Line fort to an abandoned station, from a fairground to the Amazon rainforest.
