Tony Stark is the complete playboy who also happens to be an engineering genius. While in Afghanistan demonstrating a new missile he’s captured and wounded. His captors want him to assemble a missile for them but instead he creates an armored suit and a means to prevent his death from the shrapnel left in his chest by the attack. He uses the armored suit to escape. Back in the U.S. he announces his company will cease making weapons and he begins work on an updated armored suit only to find that Obadiah Stane, his second in command at Stark industries has been selling Stark weapons to the insurgents. He uses his new suit to return to Afghanistan to destroy the arms and then to stop Shane from misusing his research.

A long time ago, far away on the planet of Cybertron, a war was being waged between the noble Autobots (led by the wise Optimus Prime) and the devious Decepticons (commanded by the dreaded Megatron) for control over the Allspark, a mystical talisman that would grant unlimited power to whoever possessed it.

To his shock, he discovers it to be Bumblebee, an Autobot in disguise who is to protect Spike, as he bears the Captain’s glasses and the map carved on them. But Bumblebee is not the only Transformer to have arrived on Earth - in the desert of Qatar, the Decepticons Blackout and Scorponok attack a U.S. military base, causing the Pentagon to send their special Sector Seven agents to capture all “specimens of this alien race,” and Spike and his girlfriend Mikaela find themselves in the middle of a grand battle between the Autobots and the Decepticons, stretching from Hoover Dam all the way to Los Angeles. Meanwhile, within the depths of Hoover Dam, the cryogenically stored form of Megatron awakens…
