A press release from the Michigan Film Office unveils an early synopsis of the film:

“As humanity picks up the pieces, following the conclusion of 'Transformers: Dark of the Moon', Autobots and Decepticons have all but vanished from the face of the planet.

“However, a group of powerful, ingenious businessman and scientists attempt to learn from past Transformer incursions and push the boundaries of technology beyond what they can control – all while an ancient, powerful Transformer menace sets Earth in his crosshairs.

"The epic adventure and battle between good and evil, freedom and enslavement ensues.”

Mark Wahlberg, who worked with Bay on his action heist flick 'Pain & Gain', is set to star, among an entirely new cast, while it's thought previous star Josh Duhamel may have a cameo.

There will also be a host of new robots to clunk alongside their human counterparts.

It's due out on June 27, 2014.
