All of the heroes were at the Raft for various reasons when a huge explosion shuts down the power. Separated, the heroes encounter villains. Iron Man is devastated by an initial attack from Graviton. Count Nefaria, Zzzax, and a few other villains keep the other heroes occupied. The group comes together when Iron Man flees from Graviton, allowing him to escape.
The heroes proceed to the Sentry. At first, they have a great deal of difficulty convincing him to rejoin society. Eventually, the heroes persistence pays off and the Sentry bolts through the ceiling, causing a collapse behind him.
The heroes are left to fend for themselves and slowly grind their way up through the levels until they reach the top of the Raft prison.
As they go up a few levels, they see that the walls have literally been painted with blood. The entire floor is deserted - except for Carnage, Tiger Shark, Vermin, and Razor Fist who are lording over a pile of SHIELD agents and inmates alike.
The heroes throw themselves into battle against this group of psychopaths. They sustain some heavy blows but, in the end, emerge victorious.
Continuing on their way up, they encounter an enraged mob of depowered heroes trying to break into the Raft's armory. Cap starts flinging his shield everywhere, Iron Man fires off his Uni-Beam, Luke Cage picks up a inmate and uses him as a battering ram, and Spidey is swinging from the rafters, kicking inmates out of his way. In no time, they have the mob subdued and dispersed.
The heroes jump into one of Tony Stark's private Quinjets and fly off to the Savage Land to get to the bottom of the matter...
