 Since none of Marylin s suitors ever get passed the front door, Grandpa decides to turn a frog into her own personal prince. A nearsighted one at that, to compensate for her  plain looks . When the rest of the family is out to the drive-in, Marylin accidentally locks herself in her room. A young man passing by mistaking thinks she is being held prisoner. The rest of the family assume the young man is the frog, turned into a prince, and promptly tie him up in the basement while getting Marylin s black wedding gown ready.
