Josie's boyfriend, Richard, is not approved by her parents. One day Josie meets Maxwell with whom she was at the Prom dance. Maxwell lives a wandering life selling driftwood art. When Richard then meets Maxwell, he gets the idea that Josie brings Maxwell home as a date for her parents' 40th wedding anniversary. The plan is for her parents to be so horrified that Josie is dating Maxwell that they see Richard in a more positive light.
A really fun romantic movie. Almost a bit of Tati philosophy in it. (It's very good even if you can't stop wondering what kind of life they will have in the "happily ever after")
