Michael Bay's fourth Transformers film, Transformers: Age of Extinction, has ditched its younger nerd-hero and moved onto salt-of-the-earth mechanic Cade Yeager, played by Mark Wahlberg, who worked with Bay on last year's Pain & Gain.
Yeager is living in Texas with his teenager daughter (Nicola Peltz) when he finds something that attracts both the Autobots and the Decepticons. Obviously, the government gets involved, too.
The trailer features all the expected Bayisms -- tough one-liners, epic battle scenes and explosions galore.
Transformers: Age of Extinction hits theaters June 27.
