Collection of five films in which the children's cartoon sci-fi series from the 1980s is brought up-to-date.
In 'Transformers' (2007) a battle rages between two camps of an alien race from the planet Cybertron - the Autobots and the evil Decepticons.
In an effort to prevent the Decepticons from gaining possession of the Allspark, a cube with the capacity to grant infinite power, the Autobots managed to smuggle the object to Earth, where they secretly hid it.
Now, hundreds of years later, with the Decepticons searching for the cube, the Autobots enlist the help of young earthling Sam Witwicky (Shia LaBeouf) to help foil the Decepticons' plans for world domination.
In 'Transformers: Revenge of the Fallen' (2009), after he glimpses the truth about the ancient origins of the Transformers through a powerful vision sent to him by the Allspark, Sam once again finds himself the target of the evil Decepticons, who have returned to Earth under the command of the formidable Starscream (voice of Charles Adler).
Joining the Autobots' mission to protect humankind is Optimus Prime (Peter Cullen), who forms an alliance with international armies for this second epic battle.
In 'Transformers: Dark of the Moon' (2011), when the Autobots discover that a Cybertronian spacecraft is hidden on the Moon, a race against the Decepticons ensues as both sides battle to reach it first.
In 'Transformers: Age of Extinction' (2014), four years after the invasion of Chicago, mechanic and single parent Cade Yeager (Mark Wahlberg) discovers what he believes to be a dilapidated truck and takes it home to repair.
However, what he really has resting in his garage is a deactivated Optimus Prime.
When government officials learn of the discovery they try to push humanitarian boundaries in the name of scientific development.
Finally, in 'Transformers: The Last Knight' (2017), with the battle between the human race and the Transformers raging on, mechanic Cade Yeager forms an alliance with English Lord Sir Edmund Burton (Anthony Hopkins) in an attempt to figure out why the Transformers keep returning to Earth.
Meanwhile, Autobots leader Optimus Prime learns he was responsible for the death of his home world Cybertron.
Desperate to make amends, he returns to Earth in search of a mysterious artefact which could bring Cybertron back to life and will seemingly do anything to achieve his goal.
