The Meg is a 2018 science fiction action thriller film directed by Jon Turteltaub with a screenplay by Dean Georgaris, Jon Hoeber, and Erich Hoeber, loosely based on the 1997 book Meg: A Novel of Deep Terror by Steve Alten. The film stars Jason Statham, Li Bingbing, Rainn Wilson, Ruby Rose, Winston Chao, and Cliff Curtis. In the film, it follows a group of scientists who encounter a 75-foot-long (23 m) megalodon shark while on a rescue mission at the floor of the Pacific Ocean.
A rescue team led by Jonas Taylor is saving a group of sailors trapped inside a sunk nuclear submarine when Jonas sees the hull of the submarine being damaged by an unknown creature. Two rescuers are stuck in the damaged submarine and say their return to the rescue submersible will take a few minutes. Taylor leaves them behind because he is afraid they will all die if they wait. As they leave, the damaged sub explodes. Taylor’s claim that a giant sea creature caused the disaster was dismissed by his teammate Dr. Heller, who believes Taylor was affected with pressure-induced psychosis and blames Jonas for the loss of their friends.
Five years later, billionaire Jack Morris meets Dr. Minway Zhang at the underwater research facility “Mana One”, which Morris finances. Zhang and his daughter, Suyin, an oceanographer, are supervising a mission to explore what may be a deeper section of the Marianas trench, concealed by a thermocline cloud of hydrogen sulfide. The mission is being conducted by Lori (Taylor’s ex-wife), Toshi, and The Wall in a submersible. The mission appears to be going well until a very large creature hits the submersible, causing it to lose contact with Mana One.
James “Mac” Mackreides, another crew member at the station, suggests sending Taylor down to attempt a rescue, citing the similarity to his story. Despite Heller’s objections, Zhang and Mac decide to travel to Thailand to recruit Taylor anyway. Suyin attempts the rescue herself, but a colossal squid intervenes. Before it can kill her, a massive shark kills it. Agreeing to help, Taylor reaches the trapped submersible, saving Lori and The Wall. However, when the giant shark returns, Toshi sacrifices himself by closing the hatch door and detaching the rescue vessel, allowing Taylor, Lori, and The Wall to escape safely while he diverts the shark’s attention to his sub, causing it to be driven into a thermal vent, causing an explosion
