Hulk is sleeping among snowy mountains when he is waken up by deer hunters. After causing an avalanche, Hulk falls into a deep pit.
Among the caverns he finds Jack Frost, the snowman. Jack sends ice statues against the Hulk. But they are too fragile for the mighty man monster. Finally, all caverns collapse burring Frost. Hulk escapes by climbing up the pit.
Meanwhile, Betty Ross, Rick Jones and Fred Sloan reach a nearby cabin where Thunderbolt Ross and Doc Samson are staying. Suddenly, Centaurus appears in the cabin, and drops unconscious. Ross accidentally shot him earlier.
