变形金刚

“霸天虎”的先遣部队旋风和毒蝎袭击了美军位于卡塔尔的军事基地，与此同时，路障帮助他的搭档迷乱潜入了美国总统的座机空中一号，通过电脑获悉，要想找到威震天就必须找到维特维奇家族的那副眼镜，上面有威震天关于能量块的信息扫描，而它现在的拥有者萨姆•维特维奇（希安•拉博夫饰）成为了“霸天虎”攻击的目标。 　　萨姆是名高中生，学校里没有人相信他讲述的关于这副眼镜的历史，失望之余，萨姆把眼镜放到网上拍卖，然而从未引起买家的兴趣。这时父亲送了一辆破车给他，这辆车恰好就是“汽车人”大黄蜂的变形。大黄蜂帮助萨姆交上了漂亮的女朋友（梅甘•福克斯饰），但很快就遭遇了“霸天虎”的袭击，擎天柱带着其他“汽车人”赶到，一场机器人大战由此拉开了序幕。A long time ago, far away on the planet of Cybertron, a war is 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 possesses it. The Autobots managed to smuggle the Allspark off the planet, but Megatron blasts off in search of it. He eventually tracks it to the planet of Earth (circa 1850), but his reckless desire for power sends him right into the Arctic Ocean, and the sheer cold forces him into a paralyzed state. His body is later found by Captain Archibald Witwicky, but before going into a comatose state Megatron uses the last of his energy to engrave into the Captain's glasses a map showing the location of the Allspark, and to send a transmission to Cybertron. Megatron is then carried away aboard the Captain's ship. A century later, Captain Witwicky's grandson Sam Witwicky (nicknamed Spike by his friends) buys his first car. To his shock, he discovers it to be Bumblebee, an Autobot in disguise who is to protect Spike, who possesses the Captain's glasses and the map engraved 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." Spike and his girlfriend Mikaela find themselves in the midst of a grand battle between the Autobots and the Decepticons, stretching from Hoover Dam all the way to Los Angeles. Meanwhile, deep inside Hoover Dam, the cryogenically stored body of Megatron awakens.
