J. Wellington Gedge seems to have everything a man could desire: a rich wife, a chateau, a life of ease in the south of France. But all he really wants is to return to California, not least because Mrs Gedge, who holds the purse-strings, is scheming to have him appointed as American ambassador in Paris, which means he will have to wear a sissy uniform. Fortunately, her plans are thwarted by a complicated series of events which involves French aristocrats, American crooks, an English novelist and the appalling Senator Opal, whose daughter, Jane, has a mind of her own.
