On the world of Cybertron, the heroic Autobots, led by Optimus Prime, are on the verge of losing their war with their enemies, the evil Decepticons, and make preparations to flee the planet. The Decepticons ambush them during the evacuation, and Optimus sends young scout B-127 to Earth to set up a base of operations where the Autobots can regroup. B-127 reaches Earth alone in 1987, crash-landing in California and disrupting a training exercise being conducted by Sector 7, a secret government agency that monitors extraterrestrial activity on Earth. S7 lieutenant Jack Burns presumes him a hostile invader and attacks, driving B-127 into the forest, where he is then ambushed by the Decepticon Blitzwing. When B-127 refuses to disclose Optimus's whereabouts, Blitzwing spitefully tears out his vocal processors and damages his memory core. B-127 manages to destroy Blitzwing before collapsing from his wounds. Before entering stasis, B-127 scans and transforms into a nearby 1967 Volkswagen beetle. Charlie Watson, a teenage outcast traumatized by the death of her father and resentful of her mother Sally for remarrying, finds B-127 in his Beetle form in a scrapyard belonging to her friend Hank, who gives it to her as a birthday present, on the condition that Charlie repairs it. In doing so, Charlie accidentally activates a homing signal that is intercepted by Decepticons Shatter and Dropkick, who had been interrogating captive Autobot Cliffjumper for Optimus's whereabouts. The pair executes Cliffjumper after receiving the signal and arrives on Earth, where they masquerade as peacekeepers to persuade Sector 7 to help them find and capture B-127, whom they claim is a dangerous criminal. Meanwhile, Charlie revives and befriends the amnesiac B-127, whom she nicknames “Bumblebee”, and teaches how to communicate through his radio. Together, they unlock a message from Optimus urging Bumblebee to defend Earth in their absence, which restores his memories. Charlie alerts Bumblebee about the importance of staying hidden, but he is later discovered by her neighbor Memo, who agrees to protect their secret due to his feelings for Charlie. Left alone, Bumblebee accidentally destroys Charlie’s living room and causes an energy spike that attracts Sector 7’s attention. Sally blames Charlie for the destruction, and she angrily leaves with Bumblebee and Memo, only to be intercepted by Sector 7 and the Decepticons and knocked unconscious while trying to protect Bumblebee. Returned home, Charlie finally expresses her pain over her father’s death and makes amends with her mother, who decoys to allow Charlie to follow Burns to a Sector 7 outpost, where Shatter and Dropkick torture Bumblebee into revealing the Autobots’ whereabouts and leave him for dead after revealing that they plan to bring the Decepticons to Earth. Charlie revives Bumblebee with one of Sector 7’s high voltage guns, and they set out to prevent Shatter and Dropkick from contacting the Decepticons. Burns and his men also attempt to stop them, but Dropkick destroys their helicopter, and Bumblebee saves Burns. After a fight, Bumblebee kills Dropkick by tearing him apart with a chain, while Charlie disables the Decepticons’ beacon, causing an enraged Shatter to chase after her. Bumblebee causes a flood, crushing Shatter under the debris, and is later rescued by Charlie. Realising he'd been wrong about Bumblebee, Burns holds off the military to allow them to escape, and Charlie, realizing that Bumblebee has a greater purpose on Earth, tearfully lets him go. After bidding their farewells, Bumblebee scans a 1977 Chevrolet Camaro and rendezvous with Optimus, who has arrived on Earth, while Charlie returns to her family. Optimus informs Bumblebee that their battle is far from over as seven more Transformers are seen arriving on Earth.
If there's a source, you should add a link And the thread you just made it's called "Bumblebee Plot" so yeah, there are clearly spoilers
First: I haven’t seen the movie yet so I may not have all the details. Second: not a fan of the premise that Optimus Prime would put mankind in harms way by knowingly bringing their war to Earth. If the Decepticons are only after the Autobots, then the noble thing to do to keep Earth safe is to not be here. Third: I still prefer the G1 approach. Earths resources are unique in the galaxy. It gives the Decepticons a reason to be here and to stay. It also gives the Autobots no alternative than to defend the planet. Honestly, it’s the ONLY storyline that requires Earth be the focal point in a situation beyond anyone’s control
