Retired heavyweight champion Jake Punchim is a fitness nut, keeping himself, his wife, and their twin daughters Helen and Dot in constant training much to Dot’s chagrin. While out walking separately one day both girls meet young men who are perfect for them but completely wrong for the other sister and make a date to meet them in the park at 2:00. When they arrive and the men mistake each sister for the other. Complications follow particularly when Daddy Jake becomes involved, but it all ends happily.
