A wealthy, spoiled woman falls off of her yacht and into the arms of a low-class carpenter who picks her up and convinces her she is in fact his wife, and mother to his four brats. Just when she learns to like her life, the tables are turned again. Even though it's all been done before, you can't help but laugh at the screwy gags.
This is one of those movies that I'm going to watch every time I find it on cable. Hawn and Russell are excellent together and Garry Marshall even manages to overcome his own shortcomings to deliver a charming love story that everyone can enjoy.
