Operation Crossbow

London officials learn of a plan by Nazis to create new, more destructive missiles during World War II. Working quickly to stop the potentially catastrophic movement, the prime minister calls for an immediate investigation. Three experts (George Peppard, Jeremy Kemp, Tom Courtenay) are instructed to enter Germany and inspect a plant that is believed to hold the explosives. The men pose as German soldiers in a mission that may save England, but not without consequences.
