The family is set to go on holiday by the Shallow Sea and stay in Mrs. Sejersen’s beach house. They have been looking forward to their holiday at the beach house, but their excitement is quickly dampened when they realize they are staying in an old circus caravan - it is no wonder that they look to the luxurious neighboring house with envy. Unjustly, Dad is accused of burglary and the family rally around him in support and with all their might they try to find the guilty burglars. As the days go by Dad looks more and more guilty and the other vacationers start to believe the allegations and try to run the family off the island.
