Ice Station Zebra

“An American nuclear sub... A sky full of Russian paratroopers... A race for the secret of Ice Station Zebra!”

A top-secret Soviet spy satellite -- using stolen Western technology -- malfunctions and then goes into a descent that lands it near an isolated Arctic research encampment called Ice Station Zebra, belonging to the British, which starts sending out distress signals before falling silent. The atomic submarine Tigerfish, commanded by Cmdr. James Ferraday, is dispatched to save them.
