Men who have come to France, separated from their children who stayed in their country, are living in a center for immigrant workers. A musician invites them to sing lullabies. Within the intimate setting of these workshops, they reconnect with buried emotions and memories. These lullabies resonate with their testimony on the complexity of paternity from a great distance and life between two countries. From far away, the voice of a child tells us the father's lack and the wound of separation.
