When advertising executive Jim Blandings (Cary Grant) discovers his wife's (Myrna Loy) plan to redecorate their New York apartment, he counters with a proposal that they move to Connecticut. She agrees, and the two are soon conned into buying a house that turns out to be a complete nightmare. Construction and repair bills accumulate quickly, and Jim worries that their future hangs in the balance unless he can come up with a catchy new jingle that will sell ham.
