The Dark Water Fever has been released by the Iron Man copy on a small scale and time is running out before it's released worldwide. The rest of Force Works simply believe their teammate is under the Mandarin's control and set out to find him.
Spider-Woman and the Scarlet Witch find the real Iron Man at work deep underwater, but so does the Living Laser who now works for the Mandarin and is spoiling for a fight. Meanwhile, War Machine, Hawkeye and Century find the Iron Man copy in a city with a spray tank full of the Dark Water Fever. Can the real Iron Man and Force Works prevent a global epidemic, or is the copy too much for even the genuine article?
