Ann Haven, an aging movie actress, receives an urgent wire demanding that she immediately return to Hollywood to star in a new film.

She plans to leave New York for Los Angeles by train, bringing along her bold young daughter, Barbara.

Romance and complications ensue — including havoc from Ann's agent Johnny Pizer, (who was also in Sunset Boulevard).

Riding high after the critical and financial success of Sunset Boulevard (1950), Swanson was offered more film roles.

Reluctant to accept the roles, in fear of being typecast as a faded actress, she agreed to be in Three for Bedroom "C" because it offered something different — it was a comedy.
