Van Johnson is Carson, a mercenary sea captain willing to do anything if the price is right, in this Cold War adventure set amidst the wilds of Greece and Albania. French bombshell Martine Carol makes her English-language feature-film debut as Tracy, the wealthy Frenchwoman able to pay Carson's price and induce him to undertake a daring rescue mission inside Communist Albania. But their troubles are just beginning when they cross the border, and the mission grows larger and more complicated when their group is taken captive by guerrillas, led by the rogue Trifon (a scene-stealing Herbert Lom). Playing a loutish, drunken first mate is a young Sean Connery, working with action director Terence Young for the first time. Five years later, Connery and Young would make film history with the franchise-defining Dr. No.
