While visiting the army to show off his new missile in Afghanistan Tony Stark is captured by a terrorist group called the Ten Rings. While captured Tony has to build a missile for the Ten Rings with fellow captive Yinsen. Instead of making a missile they build a arc reactor and a suit of armor to escape in. When the Ten Rings find out what they're doing Yinsen sacrifices himself to allow Tony to complete the suit. In anger Tony destroys the Ten Rings base and weapons. Tony flies off but crash lands and blacks out. He is found by James Rhodes his best friend. When he returns home he announces that his company Stark Industries will no longer produce weapons. Because he makes more money by selling his weapons on the black market his business partner Obadiah Stane is mad at Stark saying he going to ruin his company and his father's legacy. Back in his home workshop Stark builds and sleeker, smaller and improved version of the suit while he gets Pepper Potts to help him with the business. When at a charity event reporter Christine Everhart tells Stark about a attack on a village. He suits up and save them but on the way back he is attacked by two fighter jets, he reveals his identity to Rhodey in an attempts to stop the attack. Stane goes to the Ten Rings and gets them to gather the remains of Tony's first suit and he reverse engineers it and build himself a suit. Tony sends Pepper to Stane's office to hack his computer and find out what he up to. They find out that he been selling weapons to the Ten Rings and hired them to kill him. Pepper meets with Phil Coulson, an agent of S.H.I.E.L.D., to tell him about Stane's activities. Because his team can't make an arc reactor like Stark's Stane robs Stark's from him. So he manages to get his original which Pepper put in his workshop. Many S.H.I.E.L.D. agents try to attest Stane but he is too powerful in his suit. Tony suits up and fights Stane and defeats him with the help of Pepper. The next day Tony publicly admits he is Iron Man.
