Synopsis:
In a snow bank atop the alps, a man who has been frozen in the ice awakens and frees himself. The man walks to a nearby town where a museum is being robbed by a group of Blackhawk imposters. The man attacks them, then walks away.

When the real Blackhawks are called to the town, they recognize the man as the Iron Hammer, a Nazi they fought during World War II. The Nazi was thought to have been killed under an avalache, but now the Blackhawks know he survived.
