A United States submarine detects an off-limits submarine to see if there is any trouble. Hypnotia hypnotizes a pair of Russian sailors on the submarine, the Prometheus, so they will become an army of slaves to the evil Mandarin in a year. Around the same time, Whirlwind and Dreadknight steal a microchip and give it to Mandarin for his army of the living dead.
A year later, Tony discovers the danger that lurks in the Prometheus and the Mandarin sends out his team of super villains to stop him and Iron Man, who flies to the sunken submarine with the help of the robot IRVING. Mandarin’s team ambushes and captures Iron Man while Iron Man's own team of superheroes, among them War Machine and Century, head to the ocean to save him. This team helps Iron Man escape from both Blacklash's whip and the Mandarin's alien dragon Fin Fang Foom.
At high noon, the Mandarin finally wakes the Russian sailors, now transformed into radioactive zombie warriors. These zombies invade the Hammer Channel Tunnel in London to infect the population, but Iron Man and his team stop them by flooding the tunnel and Century returns them back to normal once they surface. Modok calls in the most powerful and destructive cyber-organism in the Universe, Titanium Man, to once again try to finish off Iron Man. Iron Man's team had thought they had defeated the villain at Magnitogorsk, but Iron Man and War Machine defeat the returned villain and they send it back into space.
- Adapted into comic book format in Marvel Action Hour, Featuring Iron Man # 1.
- The episode's title is a reference to the Bible verse Revelation 20:13: "And the sea gave up the dead which were in it; and death and hell delivered up the dead which were in them: and they were judged every man according to their works."
- The Hammer Channel Tunnel is a topical reference to the real-life Channel Tunnel, which was officially opened in May 1994, prior to the episode's debut in September that year. Creating the only fixed link between the island of Great Britain and the European mainland, freight trains commenced operations in June, while passenger trains commenced operations later in November.
