Finding the prince of the sea unconscious and trapped in a strange energy shield, Hulk travels into New York to seek the aid of Doctor Strange, the only person the brute thinks can help him.

Taking Strange back to Namor's body, they meet Necrodamus who reveals to them that he has brought them all together on the orders of the Undying Ones. He plans to sacrifice Namor when the stars are in the right alignment. He then vanishes, promising to return, and leaving Strange and Hulk to figure out how to save their ally. They cannot find a way to free him and soon the Sub-Mariner mysteriously disappears. Searching the area, they enter a cave and find Necrodamus and Namor. Necrodamus is waiting for the precise star alignment to sacrifice Namor to the Undying Ones.

Hulk attacks Necrodamus, who has now grown in size and strength, but the foe is able to strike back with his mystical dagger. Meanwhile, Strange is able to awaken Namor, who then breaks free from the inside. The two come to the Hulk's aid and delay Necrodamus long enough for him to miss the star's alignment. Failing to make the sacrifice at the right time, he disappears but promises to return.

After the battle, Namor explains that he was actually struck down by the Silver Surfer. This surprises Doctor Strange and the Defenders set out to search for the sentinel of the spaceways.
