The Robinsons are two respectable middle class parents living with their children in a suburban house in Acacia Avenue. Preferring to holiday every year in Bognor, they are pressed into booking a cruise for their annual vacation and thereby leaving their teenage children free run of their house. As the youngsters enjoy their newfound freedom and discover the angst of teenage life, Mr. and Mrs. Robinson begin to have second thoughts about their cruise and decide to return home early.
