Welcome to Sin City. This town beckons to the tough, the corrupt, the brokenhearted. Some call it dark… Hard-boiled. Then there are those who call it home — Crooked cops, sexy dames, desperate vigilantes. Some are seeking revenge, others lust after redemption, and then there are those hoping for a little of both. A universe of unlikely and reluctant heroes still trying to do the right thing in a city that refuses to care.

With the world now aware of his dual life as the armored superhero Iron Man, billionaire inventor Tony Stark faces pressure from the government, the press and the public to share his technology with the military. Unwilling to let go of his invention, Stark, with Pepper Potts and James ‘Rhodey’ Rhodes at his side, must forge new alliances – and confront powerful enemies.
