A British nuclear submarine is seized by the Russian terrorist organization the Peace Corpse led my former Russian General Illyich Prokvitch. The Avengers are asked for their assistance in retaking the submarine. They make their way to the sub and are intercepted by Russia's People's Protectorate (formerly the Supreme Soviets) who claim that this affair is their responsibility. Their battle is interrupted by an Atlantean army led by Tyrak, Meranno, and Orka.
