Review:
The billionaire funding a fancy underwater research facility visits in order to watch the first mission to explore whether the Mariana Trench is actually deeper than previously believed. It is, in fact, deeper, but celebrations are cut short as the mission submersible is attacked by a large unidentified creature, putting the lives of everyone on board at risk.
In order to save the people in the mission submersible, the team enlists the help of former rescue diver Jonas Taylor. Jonas, too, once encountered something like the creature that attacked the mission submersible, although no one believed him at the time. Unfortunately for Jonas and the research team, this rescue mission is only the beginning of their encounters with the "Meg" (megalodon, a prehistoric species of shark believed to be extinct until these characters find it).
