Ruthie, Mike, and teen daughter, Jem, live in a seaside town on Long Island. In order to afford such a lavish property they have to rent out their house for the summer to wealthy Manhattanites hungry for a summer beach experience. The family would live in a small apartment for those three months. The profit would all but pay for their house for the rest of the year. It was a great idea until the wrong person rented their home for the summer.
