As the soldiers run a convoy of special chemicals out of Chicago towards Tulsa, they are startled by the rumbling noise coming from the back of the truck. While checking the load, the Hulk jumps out of the trailer and destroys the container, spilling chemicals all over himself. Witnessing all of this is the Warlord Kaa, an alien from an undiscovered planet on the edge of our solar system. He hopes to conquer our world and believes he’s now very close (Kaa first appeared in Where Monsters Dwell #31).
Meanwhile, at the Hulkbuster base in New Mexico, a scientist named Harold Conrad, who had just found bad news from test results, got killed and place in a closet by his unknown assassin. The man grabs the results and burns them.
Later on at dawn, the Hulk is talking about how only his shadow accompanies him anywhere he goes. Kaa, disguised as Hulk’s shadow, attacks the Hulk from behind. Kaa then explains to Hulk that the chemicals spilled on him earlier have allowed Kaa to possess psychic control of the Hulk’s shadow.
The story then cuts to Betty Ross and Major Glenn Talbot enjoying a day of relaxation alongside Thunderbolt Ross as they ride New Mexico plains, enjoy rapids, swim and camp.
Back to the Hulk. It’s been eleven long hours of trading blows with Kaa who thinks he has finally claimed victory over Hulk when suddenly, he notices the sun beginning to set. His shadow growing longer, it dissolves into the night as does his mind from his body that has been orbiting the Earth in his spacecraft.
The Hulk has had a long day and finds comfort on the night Oklahoma grass and reverts to Banner. Awaking the next day, Banner heads to Hulkbuster base, only to be shot by Colonel Armbruster! He believes he is “doing good for the nation”.
