Hendrickson
Roy and Gilbert's fishing trip takes a terrifying turn when the hitchhiker they pick up turns out to be a sociopath on the run from the law. He's killed before, and he lets the two know that as soon as they're no longer useful, he'll kill again. The two friends plot an escape, but the hitchhiker's peculiar physical affliction, an eye that never closes even when he sleeps, makes it impossible for them to tell when they can make a break for it.
Capt. Mack McLoflin
Lieutenant Johnson, a U. S. Air Force pilot, on the tip of Alaska, a few miles from the Bering Straits from Siberia, helps foil a Soviet plot to test a new secret weapon by loyal Alaskan Eskimos. He is aided by Sergeant Koovuk, an Alsaka native Eskimo also in the U.S. military service. Along the way there is an ice-floe evacuation, an air-ice rescue and a fight with a polar bear.
