My Three Sons

Aeronautical Engineer Steve Douglas and his youngest son Chip face a parallel problem -- how to rid themselves of two designing females.

When Chip announces Tramp is the father of six puppies, Steve is concerned because he has never explained the cycle of life to his son. But before long a confused Chip thinks that his teacher is going to marry his father.

Steve is going on a business trip to Japan and thinks he might as well take his family along with him. Mike gets involved in a new romance with another beautiful girl named Kimiko and suddenly he forgets his girlfriend back home.

To capture the affections of a pretty blond, Robbie turns pop composer and produces a novelty song. The family agrees to do the vocal background, but when they are selected to sing the song on television, Steve gets a bad case of stagefright.

Steve sails aboard the S.S. Carolina in order to establish a business contract with a firm but his task is complicated by Robbie who has a vacationing job as a steward onboard the same liner. They both find that business and pleasure do sometimes mix.

Mike and Sally finally get married and leave for the East where Mike has a job as an assistant college psychology instructor. Robbie happily moves into Mike's old room. When Uncle Charley notes that they may soon be calling Steve 'Grandpa' he becomes somwehat concerned about growing old and calls up his former girlfriends. Robbie, now a college man, offers to help his father make friends with younger women, and while pretending to be disinterested, tries a few of his suggestions. When it is learned that Ernie must return to an orphanage, because he will not be allowed to accompany his foster parents in their move to the orient, Chip invites Ernie to move in permanently, giving Steve three sons once more.

The usually all-male Douglas household becomes a refuge for an attractive girl dancer who has been evicted from her apartment, when Steve attends an office stag dinner. He takes her home where he lends her some of Robbie's clothes.

The Douglases move to California, where at first they are depressed to find the residents as chilly as the weather is warm. Robbie enrols in the University and is totally captivated by a blonde girl, and Uncle Charley is initiated into the rapid-fire procedure of shopping in supermarkets. The family begins to feel that their next door neighbors represent the characteristic stand-offishness of all Californians until they discover that they moved into the neighborhood the day before they did.

While the family is doing some spring cleaning, Katie faints behind the couch. Soon her mother's intuition brings her to the house and she announces that Katie is going to be a mother. Once it is confirmed by a doctor, the family dotes on Katie, but seems to ignore the father to be.

Robbie and Katie move into an apartment on the next block and widower Steve Douglas becomes the target of Katie's relentless matchmaking. However, Steve meets a remarkable woman in a high school corridor and the two are quickly attracted to each other.

Chip begins studying with a pretty co-ed whose disciplinarian father wants to know why her new friend is spending so much time with her. Meanwhile, on the eve of Steve and Barbara's first wedding anniversary, Dodie announces she is throwing a surprise party, but neglects to tell everyone when or where.

Steve's look-alike Scottish nobleman cousin Fergus, comes to America looking for a bride to take back to his hometown of Sithian Bridge and moves in on the entire Douglas family, much to the dismay of Uncle Charley.
