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 £1,000. The Interceptor was arrested by the police because he went over the speed limit on the river.
