While contestant Roger tried to get his key in the middle of a maze in a stately home, the Interceptor planned an ambush. However, Roger got away before the Interceptor could zap him. Contestant Claire went on a pleasure cruise to get near her key on a river as Roger approached. The Interceptor hijacked a boat and attempted to stop them, but Roger and Claire met up within the time limit and won the ÂŁ1,000. The Interceptor was arrested by the police because he went over the speed limit on the river.
