Randolph Haven (Robert Young),an irresponsible sort, and his wife Norma (Ruth Hussey),have been married for seven years and still very much in love, although Norma is dissatisfied with their hand-to-mouth life style and gets a job as a saleslady. Randolph, seeking an easier pursuit, goes into partnership with a bookie and, in order to cover a bet, sells a manuscript on "The Psychology of Marriage", a situation that is fraught with problems, not the least being in that he didn't write the book, and that he also has to pose as a bachelor. He begins to believe in his fake personality to the extent he insists on living in a penthouse. Then the publisher falls in love with Norma, not knowing she is married to Randolph, the bachelor expert on marriage.
Married Bachelor
A man's marriage suffers when he pretends to be a bachelor while promoting "his" best-selling book about married life (actually written by an eccentric professor) in order to pay off a debt to a gangster.
