Plot
A disfigured street kid (Leonard Nimoy), a member of the Billy Goat Gang, is shown how to box by a parish priest, Father Callahan (Richard Rober), who also makes him part of the church choir. The priest introduces him to Emily. During a fight with the other members of the Billy Goats for ridiculing his church vestments, he accidentally knocks out Father Callahan, and runs away from home to avoid the repercussions. He enters amateur bouts, and then goes for plastic surgery to correct his disfigurement. After the surgery, Monk becomes even more conceited, losing the respect of Angelo and Emily, and his manager convinces him to resume fighting to address his unpaid bills.
During the comeback fight, Monk drops his dirty tactics and his opponent wins by split decision. With money going out due to Monk’s new clean tactics, his syndicate plans recoup their losses by forcing his return to dirty fighting.
In the next fight after Monk’s reform, Father Callahan and Emily are in the audience for his match against the Wildcat, which Monk loses to TKO in round 6, costing the syndicate $20,000.
Father Callahan congratulates Monk on his new ethics, and Monk and Emily reunite and marry to further Father Callahan’s sports initiative.
