Bumblebee (MalaySub)

On the planet of Cybertron, the Autobots, led by Optimus Prime, are on the verge of losing their war against the Decepticons and prepare to evacuate the planet. Decepticon forces led by Starscream, Soundwave, and Shockwave intercept the Autobots during their evacuation, and Optimus sends Autobot scout B-127 to Earth in an escape pod to set up a base of operations while he stays behind to fend off the Decepticons. B-127 reaches Earth and crash-lands in California in 1987, disrupting a training exercise by Sector 7, a secret government agency tasked with monitoring extraterrestrial activity on Earth. Colonel Jack Burns presumes B-127 to be hostile and orders his men to attack the Autobot. B-127 scans a Willys MB jeep and flees to a nearby mine, where he is ambushed by the Decepticon Blitzwing. When B-127 refuses to reveal Optimus’s whereabouts, Blitzwing tears out his voice box and damages his memory core, prompting B-127 to kill the Decepticon with one of his own missiles. B-127 scans a nearby 1967 yellow Volkswagen Beetle before collapsing from his injuries.

Elsewhere, Charlie Watson, who is depressed by the death of her father and resentful of her mother Sally’s relationship with her new boyfriend Ronald, finds the Beetle in a local scrapyard owned by her Uncle Hank, who gives it to her as an 18th-birthday present. When trying to start it, Charlie accidentally activates a homing signal that is detected by the Decepticons Shatter and Dropkick while they interrogate and kill Cliffjumper on one of Saturn’s moons. The two Decepticons head to Earth, acquire human-made vehicle forms, and encounter Sector 7; pretending to be peacekeepers, they persuade the agency to help them capture B-127, despite Burns’ objections.

As Charlie attempts to fix the Beetle, it transforms into B-127, whom she befriends and names “Bumblebee”. She then unknowingly unlocks a message from Optimus urging Bumblebee to defend Earth, which restores some of his memories. They are discovered by Charlie’s neighbor Memo, who agrees to protect their secret, while Bumblebee learns to use his radio to communicate. While left alone one day, Bumblebee unintentionally destroys Charlie’s home and causes an energy spike that attracts Sector 7’s attention. When Sally blames Charlie for the havoc, Charlie has an emotional breakdown and finally expresses her pain over her father’s death and leaves with Bumblebee and Memo, only to be intercepted by Sector 7 and the Decepticons. Bumblebee is then captured while Charlie and Memo are returning home.
