Okay, so Tony has a supersuit that gives him powers, and there are other people with superpowers who want to kill him, he still has to go to work, right?
Tony struggles to understand the rules of "the game" (at least that's what the conspiracy theorists call it) as he finds himself under attack, even as he tries to return to normal life.
One thing Tony has learned about his situation is that the different numbers on his suit give him different powers. This starts to explain how a girl can turn into a spider and how an old man's arms can stretch across the room, but it doesn't explain why he has to jab pointy objects into his eyes to win.
You probably won't understand either, but you can at least have fun seeing Tony beat up a rhino, burn down a coffee house, meet a girl (who he probably shouldn't trust) and alienate his best friend, Rod (who he probably should trust, but let's face it, he's starting to get in the way).
