The sequel reunites deep-sea rescuer Jonas Taylor (Jason Statham) with a research facility studying massive sharks in the Mariana Trench. When mating season triggers territorial conflicts among multiple megalodons and an illegal mining operation destabilises the environment, the team faces dangers extending far beyond the giant predators. The film has become a major global success on the streaming platform.

Rather than focusing solely on prehistoric sharks, the film incorporates additional creatures including fast-moving amphibians and a giant octopus wreaking havoc both underwater and on a resort. The production deliberately escalates the scale and spectacle beyond its predecessor. Statham maintains the composed, self-assured demeanour audiences expect from his action roles, delivering the straightforward heroism that makes such films satisfying entertainment.
