Clothes make the woman, as ravishing Kay Francis dazzles David Manners in her Warner Bros. debut, a stylish pre-Code romance costarring Una Merkel and Andy Devine. The hard-driving editor of The '400' Magazine, Lois Ames (Francis) is a married workaholic, as loyal to her husband as she is to her job. So when she fires her secretary for refusing to work late, Lois impulsively hires Tom Sherman (Manners), a handsome sporting goods salesman, to take her place. Rising fast in the company, Tom grows to love his work and his boss even more, a situation his jealous fiancée (Merkel) threatens to expose by telling what she suspects goes on behind closed office doors.
