Seven years ago: ballerina Purdey is about to settle down with Larry Doomer, the man she thinks is ‘Mister Right’. But when Larry's father, a trouble-shooter for an oil company, is killed in the Middle East by Arab soldiers, Larry seeks revenge by assassinating a visiting Arab dignitary. Purdey stops him, but the two of them then part ways. In the present, Purdey meets Larry once more when he is placed in charge of a fighter squadron that is putting on an aerial demonstration. The show begins, and the planes fire their missiles at their intended targets; all explode as planned, except for the missile fired from Larry's plane, which apparently detonates in mid-air. The missile has in fact been intercepted by to of Larry’s colleagues, Kilner and Morgan. When Larry goes missing Purdey realises that he must be planning to exact his revenge at long last, as the Arab dignitary he holds responsible for the death of his father is visiting London; Larry is going to launch the missile at the Houses of Parliament. Purdey guesses that the launch site is where she and Larry had once planned to build their dream house. She takes a motorbike and attempts to talk Larry out of his revenge; but Larry will not be dissuaded, and is about to kill Purdey when Gambit shoots him. As the missile begins its countdown, Steed arrives and parks his land-rover on top of the dug-out, causing the weapon to explode on the launch-pad.
