Clayton Poole is a small-town TV repairman whose former sweetheart, Carla Naples, is now a famous movie star.

Carla has cultivated a reputation as a virgin who does not have affairs or carouse with men in typical Hollywood fashion.

On a romantic fling, she secretly marries Carlos, a famous Mexican bullfighter; the next morning the couple agree it was unwise and plan to have it annulled, but her husband dies that day in a bull-fight.

Distraught, Carla tore up her marriage license, not realizing she was pregnant; there's no legal documentation to legitimize the child.

Her agent, Harold Herman tries to avoid a scandal by sending Carla into the country to give birth.

The cover story will be that she is going into seclusion to prepare for her next role, the lead in a controversial religious epic The White Virgin of the Nile.

[5][6] Cast notes: Rock-A-Bye Baby was loosely based on the Preston Sturges' film The Miracle of Morgan's Creek (1944), which starred Eddie Bracken and Betty Hutton.
