At a big city Catholic school, Father O'Malley and Sister Benedict indulge in friendly rivalry, and succeed in extending the school through the gift of a building.

Sexy, wisecracking nightclub singer Sugarpuss O'Shea is a hot tomato who needs to be kept on ice: mobster boyfriend Joe Lilac is suspected of murder and Sugarpuss' testimony could put him away. Naive Professor Bertram Potts meets Miss O'Shea while researching an article on slang and in true romantic comedy fashion the two worlds collide. When Miss O'Shea hides out with Potts and his fellow professors, everyone learns something new: the professors how to cha-cha and Potts the meaning of "yum-yum"!

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.
