Crossplot

Roger Moore is Gary Fenn, a talent scout for a London modeling agency who finds the perfect target and calculates the events which mean that only one girl will be good enough for his bosses, a Hungarian Marla Kugash (Lange). He finds her among the anti-war movement in the bohemian depths of swinging London. She is in the company of a young man, Tarquin, who is extremely protective of her and overtly aggressive to Fenn. The young Hungarian, an illegal refugee from her native homeland, accompanies Fenn to a photo-shoot. However, she admits she is in fear of her life, and seems disturbed by the presence of her aunt. When she is nearly killed, the girl drops out of sight and Fenn has to go on the run himself, suspected of a separate murder. He locates her to a country house, which turns out to be the home of Tarquin, an aristocrat in spite of his anti-war sentiments. It is revealed that Marla's aunt is part of a shadowy organization trying to destabilize the existing world order so they can take over themselves. They will go to any length to try and shut Fenn and Marla up, including sending a helicopter after them. Fenn and his friend manage to escape to London, where they realize that the shadowy movement are planning to assassinate a visiting African head of state in Hyde Park. They manage to foil the plot.
