An elderly schoolteacher is determined to rid her town of the local gambling den.

Members of a teenage gang are sent to the State Reformatory, presided over by the callous Thompson. Soon Patsy Gargan, a former gangster appointed Deputy Commissioner, arrives and takes over the administration to run the place on radical principles. Thompson needs a quick way to discredit him.

Mrs. Doray sits with a Juvenile Court Judge to learn more about problem children and what to do about them. One of the cases involves 13 year old Arthur, "the worst kid in town", who moves cars away from fiire-plugs without the knowledge of the owners. The judge gives Arthur and friend Nutty another chance. However they run into further trouble when they break into Mr. Doray's drugstore to get medicine for Nutty's grandmother. Mr. Doray is not sympathetic and completely against his wife's plan to become Arthur's guardian. More incidents occur with Mr. Doray quick to judge prior to getting all of the facts. Mrs. Doray must choose between her marriage and Arthur.
