The wife of a band leader constantly tries to become a star – in spite of her having no talent, and gets herself (along with her best friend) into the funniest predicaments.

Instead she tries constantly to perform at the Tropicana where he works, and make life comically frantic in the apartment building they share with landlords Fred and Ethel Mertz, who also happen to be their best friends.
