In Sky Riders, the off-camera tale behind the film cast a more interesting story than the film itself: when a Greek electrician died during an explosion, the film's producer, Terry Morse Jr., was arrested by the Greek government, and executive producer Sandy Howard was detained in Greece for several weeks. Finally, an out-of-court settlement was reached with the Greek government to release the film producer. The plot of the actual film has nothing to do with international incidents, although it does deal, on a comic-book level, with terrorism. The wife, Ellen (Susannah York), of an international industrialist (Robert Culp) and her two children are kidnapped from their Athens home by a terrorist group and taken to an abandoned monastery on an imposing, needle-shaped crag. The police immediately snap into action. Inspector Nikolidis (Charles Aznavour) attempts to free them, but the police force fails. Coming into the picture is Ellen's ex-husband, Jim McCabe (James Coburn). Pondering the situation, he notices a couple of crows in flight and gets a brainstorm. McCabe tracks down a flying circus of hang-gliding riders and requisitions them for the rescue. The hang gliders teach McCabe to fly, and McCabe teaches them to fight. Then, on the night of a full moon, the group glides off to the monastery to save Ellen.
