Tony Stark (Robert Downey Jr.), billionaire engineering genius and CFO of Stark Industries, the world’s largest arms manufacturer, is captured while demonstrating his latest arms in Afghanistan. Imprisoned with him is Yinsen (Shaun Toub), a doctor who saves his life by attaching a magnet that stops the shrapnel in his chest from reaching his heart. Together the pair are expected to build a powerful missile but instead build a battle suit with which to escape. How will Tony Stark's new invention (and his experience) change him…and how will the world respond?
