Model Wife (1941)

Fred and Joan are a married couple working at the Benson's business. Mrs. J.J. Benson has a strict policy against married employees, so they keep it a secret while they save every penny as they wish to have a baby. Everything goes well until Mrs. Benson decides to install her good-for-nothing son in the store and assigns Joan as his secretary. Then one day she is asked to model dresses for a late customer.
