Transformer 2007

The film begins with Optimus Prime explaining Cybertron's destruction at the hands of Megatron and his quest to obtain the All Spark. Megatron found it on Earth, but crash-landed in the Arctic Circle and was frozen in the ice. Captain Archibald Witwicky and his crew of explorers stumbled upon Megatron's body in 1897. Megatron's navigational system was activated by Captain Witwicky, and Archibald's eye glasses were imprinted with the All Spark's coordinates. Sector 7, a secret United States government organization, discovered the All Spark and built the Hoover Dam around it to mask the energy emitted by the Cube. The still-frozen Megatron was moved into this facility, and was reverse engineered to further advance human technology. In the present day, the rest of the Decepticons — Blackout, Scorponok, Frenzy, Barricade, Starscream, Devastator and Bonecrusher — have landed on Earth and assumed the disguise of Earth vehicles (except Scorponok, who hides within Blackout). Blackout and Scorponok attack the U.S. SOCCENT FWD military base in Qatar and try to hack into the U.S. military network to find the location of Megatron and the All Spark. They fail when the base staff manually sever the cable connections. While Blackout destroys the rest of the base, Scorponok chases a small group of survivors who have photographic evidence of the robots, but he is eventually repelled. In this battle, the military discovers their only effective weapon against the Transformers' armor is high-heat sabot rounds. After Blackout's failure, Frenzy infiltrates Air Force One to try again to hack into the military network, and in doing so also plants a virus. He finds the map imprinted on Captain Witwicky's glasses, which his descendant Sam intends to sell on eBay for money. Frenzy and Barricade begin tracking Sam's location. The Autonomous Robotic Organism (shortened to "Autobot") Bumblebee is also on Earth, disguised as a 1976 Chevrolet Camaro,[2] and is bought by Sam, out shopping for his first car. He helps him try to woo his crush, Mikaela Banes. Bumblebee leaves at night to send a homing signal to the rest of the Autobots, and Sam sees him in robot mode. Barricade confronts Sam and demands Archibald's spectacles. Bumblebee rescues him and Mikaela from Barricade. They leave to rendezvous with the rest of the Autobots. The Autobots — Optimus Prime, Jazz, Ironhide, and Ratchet — land on Earth and take on the forms of Earth vehicles. Sam, Mikaela, and the Autobots return to Sam's home to retrieve the glasses. Although the Autobots manage to get the glasses, agents from Sector 7 arrive and capture Sam, Mikaela and Bumblebee. Frenzy, disguised as a cellphone, secretly accompanies the group to the Hoover Dam and releases Megatron from suspended animation. Locating the All Spark, he sends an alert to the other Decepticons. Sam convinces the Sector 7 agents to release Bumblebee so that he can get the All Spark to Optimus Prime. Frenzy's virus shuts down government communications, so the Autobot-human convoy go to the nearby Mission City, to get a radio that can communicate with the air force into taking the All Spark away. The Decepticons attack, and in the ensuing battle, Bonecrusher, Frenzy, Jazz, Devastator and Blackout are killed, before Sam rams the All Spark into Megatron's chest. Optimus takes a fragment of the All Spark from Megatron's corpse, but realizes that with it destroyed, Cybertron cannot be restored. He sends a signal to other surviving Autobots in the universe, directing them to their new home, Earth. Sector 7 is closed, and the dead Decepticons are dumped into the Laurentian Abyss. The surviving Starscream escapes into space.
