After learning that his son, Yahya, has died at sea trying to get to Spain, Ahmed Tchiche must find a way to bring his remains back to Morocco so he and his family can have a proper goodbye. A Spanish mortician, an NGO worker and an established Moroccan immigrant living in Spain all struggle to help Ahmed get his son's body home. Through interweaving stories, "Until He's Back" explores a dangerous journey — crossing the Gibraltar Strait from Africa to Spain — and the difficulty of returning the bodies of those who drown at sea. In this story of grief and hope, a family and a community try to make sense of the tragedy that took Yahya away.
