Synopsis for "Age of Ultron: Book One"
The story opens with the city of New York, which looks completely obliterated, ravaged, destroyed, and above it all it floats a gigantic technological fortress.
Hiding inside the alleys of the ruined city, Avengers member Hawkeye assaults a group of Mutant Growth Hormone dealers, killing them with his arrows. Clint discovers that the group is led by the Owl and Hammerhead, who are also holding a hostage. Owl and Hammerhead head out to confront Hawkeye, who keeps his raid going forward, eliminating the members until he reaches the basement where the hostage is held and is revealed to be Spider-Man.
Owl and Hammerhead battle Hawkeye while he tries to take Spider-Man out, only to be suddenly struck by a massive shockwave caused by a fleet of mechanized sentinels in the shape of Ultron. Owl tries to reason with the sentinels, arguing that "they had a deal", while Hawkeye shoots his explosive arrows to one of the sentinels, buying him and Spider-Man time to escape as the remaining sentinels assault the place.
After their escape, both heroes arrive to a downed Helicarrier in what once was Central Park, only to be confronted by Luke Cage and She-Hulk. They hold them for Iron Man to check if they're clean from any infection from Ultron, and they are. Cage and She-Hulk argue with Hawkeye that he shouldn't have left the refuge, but Clint refused to have Spider-Man left behind and criticizes the fact that most of the remaining heroes have "given up". Iron Man points out that they have no plan, but says that Captain America is working on it (although Cap looks severely depressed and his shield is completely shattered).
For years, the heroes of the Marvel Universe have lived in fear that the rogue artificial intelligence known as Ultron would one day evolve to fulfill its desire to wipe out all organic life and take over the Earth -- that day has arrived.
