From Alistair MacLean's best-selling novel of secrets, spies and sabotage!
The U.S. nuclear sub Tigerfish churns toward the North Pole. Its mission: rescue the imperiled members of weather outpost Ice Station Zebra. On board are Cmdr. Ferraday and his crew, several unexpected arrivals with secret orders, and enough suspicions, suspense and twists to make "Ice Station Zebra" an engrossing espionage thriller
The Cold War heats up as John Sturges (The Great Escape) directs Rock Hudson, Ernest Borgnine, Patrick McGoohan, Jim Brown and more in this epic adventure nominated for two Academy Awards and featuring taut action set pieces above and below the ice. All hands to stations for excitement!

My late father, William Stewart, served as cook aboard the Sentinel amongst other boats. I was born in 1954 and Christened on the Sentinel at Grand Harbour, Valetta in the diocese of Gibraltar.
