Charge of the Lancers (1954)

"Spectacular zero hour! Adventure into the jaws of death!"

As the Crimean War rages, British Capt. Eric Evoir and Maj. Bruce Lindsey are sent to the Crimea to protect a top-secret cannon capable of blasting through the walls of a nearby Russian fort. Lindsey, unfortunately, is captured by the Russians, who subject him to brutal interrogations. It's up to Evoir to save him. Along the way, Evoir meets a beautiful gypsy girl and begins an affair as intense as the war itself.
