Meanwhile, the IMF agents keep the rightful heir to the throne, King Nicolai (Noel Harrison), under wraps, while Paris poses as Nicolai in order to throw the King's potential assassins off the track. But will the agents, including the lovely Tracey (Lee Meriwether) be able to rescue themselves before Sabattini wises up?
