King Louis XIII of France is thrilled to have born to him a son - an heir to the throne. But when the queen delivers a twin, Cardinal Richelieu sees the second son as a potential for revolution, and has him sent off to Spain to be raised in secret to ensure a peaceful future for France. Alas, keeping the secret means sending Constance, lover of D'Artagnan, off to a convent. D'Artagnan hears of this and rallies the Musketeers in a bid to rescue her. Unfortunately, Richelieu out-smarts the Musketeers and banishes them forever.

Two sailors who are always competing against each other set their sights on the same girl. When she chooses one over the other, their friendship ends acrimoniously. However, things change when one the men is in a submarine trapped beneath the ocean and the other, a diver, is sent down on a rescue mission.

Peggy and Bill are high society lovebirds, but their marriage plans are put on hold while Peggy spends most of her summer straightening out her wayward parents and her unlucky-in-love sister Janet. Mama and Papa are set to rights fairly quickly, but Janet's the one with real problems. It seems she sent some compromising love letters to a worthless cad, and now the bounder wants to use the letters for blackmail. Peggy's friend Roger and his flapper sweetheart Tootie hatch an elaborate plan to retrieve the incriminating letters and salvage Janet's reputation.
