Fleeing his battle with the Avengers, and desperate to find the Atlanteans who abandoned him, Namor finds himself atop an ice floe in the North Sea. Venting his anger at a group of eskimoes worshiping an idol entombed in ice, he hurls their idol into the ocean, never knowing the fateful act he has just performed. The Avengers, in their submarine craft, see the idol melted free of the ice and realize that it's a human being. Taking him aboard, they find to their shock that underneath his military uniform is the red, white and blue costume of World War 2 hero, Captain America! And what's more, the ice that entombed him kept him alive, in a form of suspended animation. Now, in the warmth of the Avengers' craft, he returns to life. But while the Avengers have discovered a powerful new ally, Namor is still out there, plotting the team's destruction.
