Transformers

High-school student Sam Witwicky buys his first car, who is actually the Autobot Bumblebee. Bumblebee defends Sam and his girlfriend Mikaela Banes from the Decepticon Barricade, before the other Autobots arrive on Earth. They are searching for the Allspark, and the war on Earth heats up as the Decepticons attack a United States military base in Qatar. Sam and Mikaela are taken by the top-secret agency Sector 7 to help stop the Decepticons, but when they learn the agency also intends to destroy the Autobots, they formulate their own plan to save the world.

A youth chooses manhood. The week Sam Witwicky starts college, the Decepticons make trouble in Shanghai. A presidential envoy believes it's because the Autobots are around; he wants them gone. He's wrong: the Decepticons need access to Sam's mind to see some glyphs imprinted there that will lead them to a fragile object that, when inserted in an alien machine hidden in Egypt for centuries, will give them the power to blow out the sun. Sam, his girlfriend Mikaela Banes, and Sam's parents are in danger. Optimus Prime and Bumblebee are Sam's principal protectors. If one of them goes down, what becomes of Sam?

Autobots Bumblebee, Ratchet, Ironhide, Mirage (aka Dino), Wheeljack (aka Que) and Sideswipe led by Optimus Prime, are back in action taking on the evil Decepticons, who are eager to avenge their recent defeat. The Autobots and Decepticons become involved in a perilous space race between the United States and Russia to reach a hidden Cybertronian spacecraft on the moon and learn its secrets, and once again Sam Witwicky has to go to the aid of his robot friends. The new villain Shockwave is on the scene while the Autobots and Decepticons continue to battle it out on Earth.

After the battle between the Autobots and Decepticons that leveled Chicago, humanity thinks that all alien robots are a threat. So Harold Attinger, a CIA agent, establishes a unit whose sole purpose is to hunt down all of them. But it turns out that they are aided by another alien robot who is searching for Optimus Prime. Cade Yeager, a "robotics expert", buys an old truck and upon examining it, he thinks it's a Transformer. When he powers it up, he discovers it's Optimus Prime. Later, men from the unit show up looking for Optimus. He helps Yeager and his daughter Tessa escape but are pursued by the hunter. They escape and Yeager learns from technology he took from the men that a technology magnate and defense contractor named Joshua Joyce is part of what's going on, so they go to find out what's going on.

Humans and Transformers are at war, Optimus Prime is gone. The key to saving our future lies buried in the secrets of the past, in the hidden history of Transformers on Earth. Saving our world falls upon the shoulders of an unlikely alliance: Cade Yeager (Mark Wahlberg), Bumblebee, an English Lord (Sir Anthony Hopkins) and an Oxford Professor (Laura Haddock).

On Cybertron, the Autobots, led by Optimus Prime, are on the verge of losing the Great Cybertronian War to their enemies, the Decepticons, had begin making preparations to leave the planet. The Decepticons led by Shockwave, Soundwave and Starscream ambush them during the evacuation, and Optimus sends a young scout, B-127, to Earth in order 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. Sector 7 agent Colonel Jack Burns presumes B-127 to be 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 reveal Optimus' whereabouts, Blitzwing spitefully tears out his voice-box 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 yellow 1967 Volkswagen Beetle.
