Ben, Susan and the boys are Christmas shopping in London when the tube train they are in breaks down. Whilst Susan believes she should help everybody to escape Ben just wants a drink of water and is angry when Nick refuses to give him a bottle whilst selling twelve others to total strangers. Michael meets a prospective girlfriend and Nick meets exasperated TV host Richard Whiteley and introduces him to his parents claiming that they have food. Everybody is very relieved when the train moves off at last.
