In this entry in the Lone Wolf series, the first to have a soundtrack, the jealousies of the King and the coquettish Queen are chronicled. When His Majesty learns that his wife has given the ring he gave to her to her lover, the King plans a large ball and demands the she wear the token. As her lover is a military attache, he is not in the palace, and the queen must send her lady-in-waiting to bring it back. En route, the lady meets a thief and they team up. She does not know that he has been dispatched by the King to steal ring from the attache.

Released in both a silent and a sound version: Mitch Moran, a veteran WWI pilot and now a commercial pilot, takes his young irresponsible brother, Steve, under his guidance. Steve heeds little of what Mitch is selling but does find time to steal Mitch's sweetheart Sally.
