Transformers: the Movie
The AllSpark, an ancient artifact that had created the Transformers and their home planet of Cybertron, is lost in space. Some time ago the AllSpark crash-land on a planet named Earth.
Now- the Decepticon Blackout, masquerading as a helicopter, lands on a SOCCENT base in Qatar. He transforms and attacks in an attempt to hack the US Military database. The base commander, Colonel Sharp, severes the hardlines before the Decepticon could download all the data. Blackout obliterates the base, but a small band of survivors led by Captain Lennox escapes. Blackout dispatches Scorponok to hunt them down, since they had caught a thermal photograph of him.
Meanwhile, an average teenage boy named Sam Witwicky is saving up to buy a car. A genealogy report reveals that Sam is the great-grandson of Archibald Witwicky, an Arctic Explorer. Afterwards, his father takes him to buy a second-hand car. The Autobot Bumblebee, disguised as a beat-up old Camaro, arrives on the car lot. After smashing the windows of all the other cars in the lot, Sam and his father buys Bumblebee. Sam then uses his new car to impress the girl of his dreams, Mikaela Banes, when she was dumped by her boyfriend. Bumblebee helps Sam out with some quirky tricks.
Meanwhile, Scorponok assaults Captain Lennox's team and kills Donnely, as well as possibly several others as well. Lennox, Epps, Figueroa and the remaining soldiers reach a settlement. Epps and the others manage to hold Scorponok back while Lennox contacts the Pentagon. An air strike arrives, and Scorponok escapes after being assaulted with high-temperature shells.
Secretary of Defense John Keller arranges for them to be retrieved, while he assembles a team of computer experts to determine the attackers. Maggie Madsen, one of the experts, insists that the attackers must be alien or something similar, but she is ignored. Meanwhile, the tiny Decepticon Frenzy sneaks aboard Air Force One and nearly succeeds in downloading the database. However, Maggie and her team discover this, and they manage to cut off the connection before Frenzy could finish downloading. Frenzy, however, comes across a classified file called 'Project Iceman', as well as about Archibald Witwicky. After killing several agents and making his way out of Air Force One, Frenzy rendezvouses with Barricade. Together, they learn the existence of Archibald Witwicky and his glasses (now sold on Sam's eBay page), which had Cybertronian language imprinted on it. The duo heads off to hunt down Sam.
Maggie Madsen had downloaded the classified data of Blackout and Frenzy's signatures and takes it to her fellow hacker Glen Whitman. But before they could decipher much, government agents storm in and apprehend them.
Bumblebee heads off alone at night to contact his fellow Autobots in space. Sam, thinking that his car had been stolen, follows in pursuit. He witnesses Bumblebee transform, and is freaked out. The police that take him in for questioning passes this off as drugs or something similar. The next day, a driverless Bumblebee returns to Sam's house. Convinced that it is 'Satan's Camaro', Sam runs away from Bumblebee, only to be cornered by Barricade, who questions him about the glasses. Sam manages to escape, running into Mikaela on the way. The two escape with Bumblebee, who Sam trusts to some capacity. At an abandoned power plant, Bumblebee and Barricade both transform and battle, while Frenzy attacks Sam. Mikaela manages to behead Frenzy with a chainsaw, while Bumblebee defeats Barricade. Sam and Mikaela discover that Bumblebee can only talk through the radio, and decides to trust and go along with the Autobot. However, Frenzy's head is still able to move and hitches a ride in Mikaela's handbag, disguised as her mobile phone.
After upgrading his alternate mode to a concept Camaro, Bumblebee takes the humans to witness the arrival of Autobot reinforcements—Autobot leader Optimus Prime, first lieutenant Jazz, weapons specialist Ironhide and the medic Ratchet. After scanning alternate modes, they meet Bumblebee and the humans at an abandoned alley. Optimus tell the humans about the war, and that the AllSpark had crash-landed on Earth years ago. The leader of the Decepticons, Megatron, had followed the AllSpark to Earth but is entombed in the Arctic. Archibald Witwicky had apparently discovered Megatron's body, accidentally activating some of Megatron's systems, which imprinted the AllSpark's location on his glasses (as well as driving him insane).
Sam, Mikaela and the Autobots head back to retrieve the glasses from Sam's house, but before the humans could give the glasses to Optimus a government agency named Sector Seven arrives and arrests Sam, his family and Mikaela. The Autobots arrive and manages to disarm the initial wave of agents led by Agent Simmons, but reinforcements equipped with specialized weapons manage to knock down Bumblebee, who had broken cover to save Sam and Mikaela from plummeting to their deaths. Bumblebee, Sam and Mikaela are subsequently captured.
Another Sector Seven agent, Tom Banachek, contacts Keller and convinces him of alien involvement. However, a virus inserted into the system by Frenzy earlier on activates and takes out worldwide communications. Banachek takes Keller (as well as Maggie and Glen) and Lennox's team to Hoover Dam. Simmons also takes Sam and Mikaela there. Meanwhile, Optimus Prime proposes that if all else fails, he would merge the AllSpark with his own spark to deny Megatron from obtaining its power.
Simmons and Banachek show the others top secret discoveries that the agency had hidden for years. The frozen Megatron, as well as the AllSpark itself. After a little demonstration of the AllSpark's ability to create feral life from existing technology, the power in the Dam begins to give out. Frenzy had wandered off and had discovered the AllSpark. His body restored, Frenzy contacts Starscream, who mobilizes the rest of the Decepticons.
Sam and Lennox manage to convince Sector Seven to release Bumblebee after an aggressive stand-off. Bumblebee shrinks the AllSpark into a football-sized cube, and along with Lennox's team they head off to nearby Mission City.
Frenzy, meanwhile, deactivates the cooling systems holding Megatron in place, while Starscream opens fire on Hoover Dam's power station. Megatron is released and meets up with Starscream, not too impressed with his second-in-command's performance. Simmons, Keller, Maggie and Glen try to find a way to contact the air force, but are assaulted by Frenzy.
Barricade and Bonecrusher try to intercept the convoy (who had been joined by the Autobots). Bonecrusher tears through several vehicles and engages Optimus Prime, but is quickly beheaded. The convoy, minus Optimus, reaches Mission City. Starscream strafes them, tearing Bumblebee's legs apart in the assault. Meanwhile, back at the Hoover Dam, Glen manages to get a morse code message to the air force, while Frenzy's face is cleaved apart by his own ricocheting projectile. The battle in Mission City did not fare well with Devastator's arrival, who takes all three Autobots to hold back. Blackout and Megatron soon join the fray. Jazz tries to hold off Megatron, but the Decepticon leader kills the valiant Autobot. Sam races to pass the AllSpark to a military airlift. Ironhide and Ratchet are knocked down by Starscream, and Sam is faced alone to confront Megatron. Optimus Prime arrives, and saves Sam from falling down several stories. Optimus Prime and Megatron begin to battle, tearing through buildings in the process.
Meanwhile, Mikaela jury-rigs Bumblebee to a tow truck, and with the help of Lennox's rangers, manage to kill Devastator. The air force arrives, and although Starscream manages to kill some of them, they (along with Captain Lennox's attack on Blackout's unarmoured chest) manage to launch an airstrike that kill Blackout.
After a long battle, Sam thrusts the AllSpark into the damaged Megatron's chest, overloading the Decepticon leader and killing him. Optimus laments Megatron and Jazz's deaths, and pulls out the remaining AllSpark sliver from Megatron's corpse. Bumblebee stays with Sam as his guardian. After the battle, Sector Seven is disbanded by Keller and the president, while the remains of the Decepticons' bodies and dropped into the Laurentian Trench. Optimus Prime sends out a message calling the other Autobots to Earth.
Meanwhile, the mostly undamaged Starscream flies into space, while Sam's parents are interviewed by a television channel, but did not reveal anything.
