Forced downstream, Allie and his family arrive at the coast. Mother and the children rejoice, believing they can return to the United States. Allie, refusing to believe his dream has been shattered, announces that they have all they need on the beach and tells them that the United States has been destroyed in a nuclear war. Settling on the beach in a houseboat he has built, and refusing assistance from Mr. Haddy, Allie believes that the family has accomplished building a utopia. One night, the storm surge from a tropical cyclone nearly forces the family out to sea until Charlie reveals that he has been hiding motor components (secretly given to him by Mr. Haddy), allowing them to start the motor on the boat.
