Aeronautical Engineer Steve Douglas and his youngest son Chip face a parallel problem -- how to rid themselves of two designing females: Widower Steve is introduced to attractive and eligible Pamela MacLish, and is pursued by her because she wouldn't mind being the new Mrs. Douglas. Steve's youngest son Chip, aged eight, has similar problems with his classmate Dorine Peters, who would love to be his steady girlfriend. Pamela decides to call upon Steve with some leftover cake from their dinner, only to be met with a rambunctious houseful of children. Michael O'Casey, Steve's father in law, affectionately known as 'Bub' attends to the household chores. The eldest son Mike, aged eighteen and named after his Grandfather, is talking on the telephone, while middle son Robbie, aged fourteen, plays with the family's shaggy dog, known as Tramp. Before long Steve is accompanying Pamela and Chip to Chip's grade school dance. Chip takes it upon himself to give his father some sonly advice. Me (thetvdb.com)
