Here's what I get out of that trailer, basically the entire movie they just showed and I haven't seen it yet.
Sam get's shown something secret like a connection device that is like the spark connected to locate transformers and the humans are secretly trying to destroy them all. Sam spills his guts about the knowledge he was shown in the facility and his girlfriend gets captured. Mean while a dumb scientist activates the spark sending the energy to the moon causing all of the machines on the moon to come back and destroy the source or capture the source holder. Which creates a jointed war between the autobots and Decepticons to destroy this new enemy trying to destroy both humans and any machine that poses a threat. Trailer was good don't get me wrong but I'm not 100 percent if I want to see it.
