To avenge the brutal murder of his brother, Jake Ray journeys to the Philippines, where his search for truth finds him battling both in and out of the ring. But the weapons are always the same: bare fists, bare feet. And the rules never change: last man standing wins.
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 (Rock Hudson), is dispatched to save them.
