"She" is secretary Claudette Colbert and "Her Boss" is Melvyn Douglas. Once married, Colbert discovers that Douglas expects her to work as usual. She must also contend with his wealthy, snooty family, whose most hateful member is his spoiled brat of a daughter (Edith Fellows) by a previous marriage. Rebelling against her repressive existence, Colbert eventually puts her in-laws in their place and arouses the ardor of the "strictly business" Douglas. While consistently amusing throughout, the highlight of She Married Her Boss is a first-reel bit of pantomimic whimsy involving Claudette Colbert and a roomful of department store mannequins.
