Father O'Malley the unconventional priest from 'Going My Way' continues his work for the Catholic Church. This time he is sent to St. Mary's, a run-down parochial school on the verge of condemnation. He and Sister Benedict work together in an attempt to save the school, though their differing methods often lead to good-natured disagreements.
