The real-life marriage between Dick Powell and Joan Blondell was already on the rocks when they costarred in Model Wife. The story is "Working Girl Plot No. 6": Blondell's employer frowns upon married women working. She's married to Powell. The marriage must remain secret. The boss has a "thing" for Blondell. So does every other man. Powell fumes. Complications. Movie ends happily. And that's Model Wife, the second and last of the Powell/Blondell vehicles of the 1940s (the other film was titled, significantly, I Want a Divorce).
