A prison-camp convict learns that his younger brother will soon be joining him behind bars.

Annie (Ann Gillis), an orphan, (based on Harold Gray's comic strip but who is at no point in the film called 'Little Orphan Annie), is befriended by a fight manager, 'Pop' Corrigan (J. Farrell MacDonald). She brings him Johnny Adams (Robert Kent), a promising prizefighter. Annie gets the people of the neighborhood to finance his training. But on the night of Johnny's big fight, a gambling syndicate locks him in a gymnasium and it appears the neighborhood folks will lose their investment.
