Dr. Emma Collins and her team are spending their third summer on the island of Little Happy studying the effect of climate change on the great white sharks who come to the nearby nursery every year to give birth. Along with the last two inhabitants of this former fishing village, their peaceful life is disrupted when a "scientific" team led by her ex-boyfriend and marine biologist Richard show up looking for three bull sharks who we soon learn aren't just any bull sharks.

Why it matters

A mid-tier shark thriller that leans into creature-feature carnage over character depth, offering enough fin-infested thrills to satisfy genre enthusiasts.

  • Embraces the “sharks on a vengeful killing spree” angle with improved CGI and splashy set pieces compared to its immediate predecessor.
  • Environmentalist subplot clunks under cliché, but grounds the film in contemporary climate anxieties—shark horror meets eco-consciousness.
  • Performances are uneven, with some cringe-worthy preachiness, but Tania Raymonde anchors the cast with steady presence.
  • Best for viewers who want a lean, bloody shark flick without the narrative ambitions or scares of the original Deep Blue Sea (1999).
