The experiences of a disparate group of young men as they make their way through Navy boot camp.

After winning the heavyweight championship, boxer Duke Foster (Allan Lane) quits the ring to marry socialite Susan Corbin (Heather Angel). When his businessman father-in-law Arnold (Frederick Burton) loses his fortune, Duke returns to the ring to raise money for him. Susan is furious that Duke is breaking his promise never to box again, and the stakes get even higher when a crooked promoter orders him to take a dive ... or else.
