Tony Stark is not only a billionaire playboy, but an ingenious engineer as well. He has a shrapnel in his chest, after being wounded and kidnapped in Afganistan, where he demonstrated a new missile produced by his company. Instead of assembling weapon of mass destruction for his captors, Tony creates a powered suit of armor to save his life from shrapnel and escape captivity. After returning to the U.S.A. he decides to stop the production of weapons by Stark Indistries, but his associate Obadiah Stane keeps selling weapons secretly. Tony updates his armor and stops Stane.
