The plot: The underwater research facility Mana One, led by Dr. Minway Zhang (Winston Chao) and his daughter Suyin (Li Bingbing), have discovered a previously-uncharted area of the Marianas trench that is even deeper than the current record. As they send a team down to explore the new depths, they soon find evidence of a Megalodon, a gargantuan shark thought to have been extinct that is far from dead. The mission, the facility, even the entire world could be in jeopardy if the Meg makes it to the open seas, and it's up to retired rescue diver Jona (Jason Statham) to stop it.
