DESCRIPTION: Remember Chicago. Following the city’s devastation during the last battle between the Autobots (the good guys) and the Decepticons (the bad robots), the world wants nothing to do with the Transformers who have now gone into hiding. But as luck would have it, a jacked mechanic Cade Yeager (Mark Wahlberg) stumbles upon Optimus Prime (Peter Cullen), leader of the Autobots, while looking for scrap parts. Cade may be from meager circumstances and perpetually dressed in oil stained tees and jeans but with Optimus Prime by his side, he’s in for a dangerous adventure rife with threats from both the human and Decepticon worlds. Chicago is the third most populous city in the United States, with 2.7 million residents. Sometimes called Chicagoland, the city and its neighboring areas play host to leading American universities, medical centers and cultural hubs including the Symphony Center and the Millennium Park.
