Tony Stark (Robert Downey Jr.) was born into a wealthy family in New York, and as he stretched out his hands to open his mouth from his coat, he didn't know how to play hedonistic like all the idiots. The naturally intelligent Stark was a surprising genius, graduating from the MIT Power Engineering Department at the age of 17 and successfully finding his social identity with impressive results - the new owner of his family business Stark Arms.
The unfortunate death of his parents has inspired Tony's career. At the age of 21, he began to control tens of billions of assets, and gradually established Stark as the first arms supplier of the US military. But Tony's arrogant personality and unscrupulous approach to his ends often caused him a lot of trouble.
Fortunately, he also has a shrewd and sexy female assistant, Virginia Potts (Gwyneth Paltrow), who always gives him meticulous care and help. He was keen to get high-class celebrities or models of all kinds into bed, and then the next day asked his secretary, Pep, to throw away the overnight "garbage".
But a kidnapping soon after completely changed Tony Stark's life. When Tony led a team of his men and military observers to test his latest developments in the deserted areas of Afghanistan, he was attacked by terrorists.
Eventually, Tony, who was hit in the heart by shell fragments in the chaos, wakes up to find a strange device in his chest that keeps him alive.
Dr. Inson, who was also a hostage, used a car electromagnet to suck the shrapnel from his body, saving Tony Stark's life, and of course, the terrorists who saved him asked Tony Stark to create more powerful weapons for them. Good guys don't eat the losses in front of them, and smart Starks don't sit still.
After being kidnapped, he began to suspect the weapons industry on which he depended, and after being injured by his own weapons, he began to understand the dangers of weapons, so the first thing he escaped was to announce that Stark Industries had given up making weapons.
Therefore, with the help of Inson, he used the rough equipment and raw materials provided by the terrorists to build steel armor for himself in the dark underground base, and in the firefight with the terrorists, Dr. Inson bought time for Stark to escape and died, but made the escaped Tony change his idea of making arms to save the world and conduct other scientific and technological research.
So he improved the steel armor, created another piece of fusion energy, became the real Iron Man, and after a test flight, improved into a truly integrated armor. At this time, Obadia Stein (Jeff Bridges), a bad guy who has been coveting stark's rich man for a long time, can't hold back and makes a big splash in the Stark arms company, secretly trading with the terrorist leader.
After being rescued and returned to Malibu, USA, Stark and AI (Jarvis) built a new Ark Reactor, but an accident occurred in Malibu when changing the Generation Ark Reactor, causing a copper wire to short-circuit in the body, which was finally removed by Poz and returned to Tony by her as a souvenir.
When the military discovers that stark, which has been declared closed, continues to engage in the arms trade, Tony learns of this and travels to the areas controlled by terrorist groups to rescue civilians. On the way back, intercepted by the military, the battle in the air can not be said to be the most exciting scene in the movie. Back at home, he arranged for his assistant Potts to infiltrate his original office and copy the system data in the computer, but Obadiah Stan did not notice the copy data, and waited for Potts to leave the office before waking up from a dream and began to hunt.
Downstairs, sitting downstairs is Phil, an agent who wants to woo Iron Man, and Potts takes him to find the monster robot that Obadiah Stan has developed in Laboratory 16.
Obadiah constantly persuaded Stark to hand over the Ark reactor design or patent it, but Stark repeatedly refused. After attempting unsuccessfully to commission the rest of Stark's scientists to replicate the Miniature Ark Reactor while brutally recovering Stark's Mark 1 wreckage in the desert and beginning a rebuilding plan, he seized the Ark Reactor in tony Stark's residence in Malibu that night after paralyzing Tony in Malibu.
Potts and agents rush to Laboratory 16, and Tony knows that the female assistant is in danger and immediately flies over to rescue her. In the laboratory to engage in fierce hand-to-hand combat, Tony wants to fly into the atmosphere of the ice to suppress O badia's pursuit, the two sides are still tied, the monster robot is more than twice the size of Iron Man, it is inevitable that the other side's attack. Use the phone to ask the "girlfriend" for help, set the power of the laboratory equipment to the maximum, use the energy of the reactor explosion to attack Obadiah just above, and finally win.
At the end, the military puts himself in The shoes of Tony to hide Iron Man's identity, but Tony uncharacteristically announces to the world: "I'm the iron man!" "
I thought the movie would end like this, but this laid the groundwork for the opening of the Marvel hero movie.
