...If Atlantis Should Fall! Continuing from last issue... Red Ghost and Attuma have captured the Defenders Sub-Mariner, Valkyrie, and Hawkeye along with Professor Jennings in an attempt to capture Atlantis. The Red Ghost has managed to turn Namor into his mindless slave and sets him against his two comrades, who are easily defeated and prepared to be subjected to the same treatment.
Two weeks later, Dr. Strange has returned to his Sanctum Sanctorum to inform Clea and Wong that he has found a method that may free the Black Knight from his stone prison and so begins summoning the Defenders to aid, however the only Defenders he is able to rouse are the Silver Surfer and the Hulk. While back under the sea, Red Ghost and Attuma have finished their mind control over the captured Defenders and are plotting to use them in their attack against Atlantis. On the surface, as the other Defenders mull over what to do about Val and other others, the Hulk mentions he might know where they went. Dr. Strange casts a spell to help the Hulk remember, and learns that they were captured by Attuma and taken under the sea, and the Hulk didn't go after them because he is afraid of water. Putting the Hulk to sleep, the Silver Surfer and Dr. Strange fly off to rescue their captured comrades.
The two heroes arrive just in time to see that their friends are being used as pawns in Attuma's attack on Atlantis. Freeing their friends from the Red Ghost's mind control, Dr. Strange and Silver Surfer then combine their powers to block the flow of cosmic rays into Earth's atmosphere which causes the Red Ghost's powers to fade. The Defenders make quick work of Attuma and the Red Ghost, then turn back the invasion against Atlantis. With their foes defeated, the Defenders leave to return Professor Jennings home.
