When he finds that his little sister has begun to discover boys and that his dim witted men don t think they can handle her, he vows to escape. After he eludes the manhunt, he accepts a job to smuggle gold into the country for which he assembles an entire movie company, including an aging star (Victor Mature) for cover as he manages to stay several steps ahead of the authorities. Little sister, in her own way manages to keep up with him nicely.
