Daytime Wives.

Ruth Holt is the efficient private secretary to young architect Elwood Adams. Her polar opposite is Adams' indolent, spendthrift wife Francine, faults which Adams, blinded by his love for her, doesn’t see. Looking to cause trouble, a lounge lizard acquaintance of Francine’s spreads gossip to make her jealous of Ruth. In a business crisis Adams introduces Ruth as his wife to banker Amos Martin but when Francine finds out she flies into a rage and denounces Ruth. After a series of complicated events Ruth reunites the Adams couple and marries the banker.
