Jackson Slate, famous treasure hunter, is out to find the legendary Lost Gold Of Cortez in the open waters off a secluded island in the Caribbean Sea. Using dynamite to blast his way through centuries of silt, new chasms are created reaching miles below the ancient ocean floor. From here, an ancient evil is released, that quickly, savagely, and without warning, destroys Jackson s boat and kills his crew. The sole survivor of the carnage, Jackson teams up with marine biologist, Sarah, to venture back to the site and investigate the horrific events. They extract an egg from the darkest depths of the ocean and take it back to the lab to investigate. But when it hatches, they realise they have awaken a deadly prehistoric monster, the P-Rex, which will stop at nothing until the entire island is destroyed...

Why it matters

A no-frills creature feature that blends treasure hunting with prehistoric monster mayhem, delivering exactly what low-budget sea monster fans crave.

  • Practical effects and CGI mix with a charmingly unpolished aesthetic that recalls early SyFy creature flicks.
  • Perfect for viewers who revel in B-movie schlock with a dash of campy island adventure.
  • A throwback to ’90s creature-on-the-loose tropes, tapping into the primal fear of ancient evils beneath the waves.
  • Not for the narrative purists, but an entertaining dive into genre comfort food with plenty of teeth and claws.
