The official synopsis of Iron Man 3 goes like this:

Marvel Studios’ Iron Man 3 pits brash-but-brilliant industrialist Tony Stark/Iron Man against an enemy whose reach knows no bounds. When Stark finds his personal world destroyed at his enemy’s hands, he embarks on a harrowing quest to find those responsible. This journey, at every turn, will test his mettle. With his back against the wall, Stark is left to survive by his own devices, relying on his ingenuity and instincts to protect those closest to him. As he fights his way back, Stark discovers the answer to the question that has secretly haunted him: does the man make the suit or does the suit make the man?

I’d say the trailer does a pretty good job of portraying that and I look forward to seeing if Tony Stark can move beyond being such an insufferable tool and learn something from his new “teacher”… Take a look and tell us what you think.
