Pat McGinnis (Victor McLaglen) murders a policeman and escapes by committing a more minor crime, for which he is arrested and jailed. An innocent man, Michael O'Keefe (Barry Fitzgerald), is convicted of the murder and sentenced to death. While delirious after an injury, McGinnis confesses to priest Father Loma (Joseph Calleia). Loma, whose flock includes McGinnis's girlfriend Molly Sullivan (Sally Eilers) as well as the O'Keefe clan, struggles to find a way to save O'Keefe without violating the sanctity of confession. He must convince McGinnis to give himself up.
