Cannon's team fell before the superior might of the mysterious stranger attacking the Chernobyl Nuclear Reactor. Now, StormWatch One steps up to meet the challenge, but are they prepared for what they will find? Meanwhile, Malcolm, Battalion's younger brother, meets his instructor.

Battalion, Hellstrike, Fuji, Diva and Cannon arrive in a nuclear plant in Chernobyl to save some of their teammates from Stormwatch, battle an alien tyrant named Regent and prevent the nuclear plant from going into meltdown. They are able to fight off Regent, who teleports away to safety. They rush to stop the imminent meltdown but learn that Fuji, who was tossed away during the battle against Regent, has been able to place the control rods so that the meltdown won't occur.
