We don't know too much about how the threequel will continue from Fallen Kingdom's cliffhanger that saw dinosaurs out in the world.
After its trip to the Cretaceous period, the IMAX footage ends with a T-Rex crashing through a drive-in cinema in the present-day. It's that Trevorrow admitted to EW has become "meta in a way that was never planned" after drive-in cinemas were the only ones open during a lot of the past year.
The teaser footage still doesn't really give us too much of an idea what to expect from the movie though as the plot is being kept under wraps.
