In Meg 2: The Trench, Jason Statham's Jonas once more has to stop giant sharks from devouring pockets of vacationers outside of China. This time, he has more human enemies to contend with in a modern spin on the Jaws franchise. It's all thanks to his company having an evil investor, Sienna Guillory's Driscoli. She sent a secret team down into the Trench for illegal metal mining, which leads to an explosion that creates a hole in the thermal barrier that keeps the creatures in their habitat.
