The East Side Kids find a young girl in the apartment of a man who has just been murdered. Believing her to be innocent, they hide her in their clubhouse while they try to find the real killer. The killer, however, used a baseball bat as his murder weapon, and the bat has the fingerprints of one of the gang on it.
