Occupied by a client, Lise, a parisienne call girl, is unable to accompany her son to a concert his choir is conducting. The boy leaves for the church alone, but is hit by a car on the way and falls into a coma. Convinced that the miracle of the virgin of Abberville can save her son, Lise asks father André to accompany her on a pilgrimage to this village in the north of France. The old priest, who doesn't believe in the fantastic stories of miracles and the supernatural, refuses to help her. Thus, only at gunpoint does father André consent to make the trip.
