 The routine of a group of fledgling boxers all living in Ma Galestrum s boarding house is interrupted when Ma allows her roving niece, beautiful Judy Galestrum, to move in. Especially interested is ex-college boy Ken Burke who is trying to quickly make it to the top, and young brawny Swedish janitor Olaf Jensen who believes Judy will fall for him if he becomes a champion boxer. The rivalry between the two friends leads them to an inevitable meeting in the ring.
