It seems that Harvey Miller, Jr (Jerry Lewis), son of a famous pro golfer, is a talented player in his own right--except for one major handicap: the guy gets so shy in front of a crowd that he's unable to make contact with the ball. Enter his girlfriend's brother, the suave Joe Anthony (Dean Martin), who is not shy on the course with the clubs or with the ladies when he's off the links. Harvey becomes Joe's caddy and coaches him to the finals of a huge pro tournament where Joe falls for the beautiful club secretary, Kathy Taylor (Donna Reed).

As usual, Jerry finds himself in the rough while Dean swings with his typical grace in one of the duo's finest films, featuring the hit, "That's Amore".
