Transformers: Revenge of the Fallen (2009)

It’s been two years since Sam Witwicky (Shia LaBeouf) and the Autobot army rescued humanity from the Decepticon invaders. Now Sam is busy preparing for the biggest goal in life: college away from home.
Away from home is also something that Autobot knows better. Hoping to recreate his home planet Cybertron, which has flushed with The Spark, the Autobots land on the planet, allied with the NEST army to scrutinize and destroy the remnants of the Decepticon remnants at Earth. Sadly, the desire to live peacefully beside the humans of the Autobots is not acceptable.
National Security Advisor Theodore Galloway said that the presence of autobots would endanger humanity and seek to get rid of all Transformers out of the earth and disband the NEST. Optimus Prime, the leader of Autobot, agrees to leave our planet at the will of the government, and also warns Galloway to handle self-inflicted events after Autobot is no longer on guard to protect the earth again.
With the help of the Autobot side, NEST soldiers and former Simmons agents, Sam and Mikaela, must find historical secrets of the Transformers presence on Earth, and protect the planet from the revenge from the ancient Decepticon name The Fallen.
