Count Five and Die is a neat British-made programmer set just before the D-Day invasion. Nigel Patrick plays a British major who heads a group of special agents, dedicated to misleading the Nazis into thinking the invasion will take place in Holland. The Allied spies, which include American Jeffrey Hunter and Frenchwoman Annemarie Duringer operate under cover as the owners of a documentary filmmaking firm. The plan is nearly destroyed when one of the spies turns out to be a Nazi agent. The title Count Five and Die refers to the length of time its takes for the traditional cyanide capsules (always doled out to secret agents in films of this nature) to take effect.
