In 1714, Captain Zachariah Zicari (played by Liam Neeson) was on a mission to stop a group of possessed townsfolk from using a powerful amulet that would have released the ultimate evil, the Leviathan. With the help of his crew, Captain Zicari was successful in stopping the ritual and securing the amulet.
Fast forward to 2014, the amulet has resurfaced in the wrong hands and is being pursued by a group of criminals led by a mysterious figure known only as "The Collector". When the Collector and his henchmen break into a museum to steal the amulet, they are confronted by Captain Z and his descendant, a marine biologist named Zack Zicari (played by Chris Hemsworth).
As they battle for possession of the amulet, a series of supernatural events occur, indicating that the Leviathan has been awakened. With time running out, Captain Z and Zack team up to stop the Leviathan from destroying the world.
Along the way, they are joined by a group of unlikely allies, including a young psychic named April (played by Emma Stone) and a reformed thief named Jack (played by Tom Holland). Together, they must navigate treacherous waters and face their greatest fears to save the planet from the Terror of Leviathan.
As the final battle between good and evil approaches, Captain Z and Zack must make a choice that will determine the fate of humanity. With the help of their friends and their unwavering courage, they go head to head with the Leviathan in an epic showdown that will leave audiences on the edge of their seats. Will Captain Z and Zack be able to save the Earth? Only time will tell.
