A fearsome rumour reaches Britain's World War II command. The Nazis are developing rocket technology that could rain death on London and, then, New York. Quickly, England develops a plan to send saboteurs into the sites manufacturing the rockets. Just moments after the carefully chosen commandos parachute into the drop zone, their pilot receives an urgent message: The mission may be compromised. Abort. Operation Crossbow is the partly fact-based tale of how that team succeeded against daunting odds. Michael Anderson directs guiding a huge cast in a film that builds to a spectacular finale, yet never neglects war's unsparing personal costs. As a record of a wartime espionage incursion and as an intrigue-filled thriller, Operation Crossbow is on both counts Operation Accomplished.
