Paradise turns deadly in the new trailer for The Devil’s Mouth, trapping a group of friends with summer’s deadliest movie monster: sharks.

The Devil’s Mouth debuts globally on Prime Video on July 29.

In the film, “Five friends set out on one last adventure along Thailand’s stunning coast, eager for a final thrill before life in the real world begins. They sign up for a guided swim through a remote cave system known as The Devil’s Mouth, a natural wonder that’s as breathtaking as it is unforgiving. Deep inside the labyrinth of narrow waterways, their journey takes a terrifying turn when they discover that a freak storm the week before flooded the caves with sea life.

The creatures died in the fresh water, but something survived… and it’s hunting them now— fast, silent, and deadly. Every corridor they round is overflowing with anxiety, and every wrong turn becomes a deadly encounter. As panic spreads and their sense of direction slips away, the group begins to fracture. Trust erodes, fear takes over, and survival becomes a savage game. In the suffocating darkness, every choice could be their last as they learn that to make it out alive, sacrifices must be made.”

Jeff Wadlow (Truth or Dare, Imaginary) directs the shark attack movie from a script he revised from Aja Gabel (“Sunny”) and Myung Joh Wesner (“Star Wars: Skeleton Crew”).

Kathryn Newton (Abigail, Lisa Frankenstein, Ready or Not 2: Here I Come), Lana Condor (Pretty Lethal), Nico Hiraga, Gavin Casalegno, Tommi Rose, and Tayme Thapthimthong star.

The upcoming survival thriller The Devil’s Mouth has been rated PG-13 by the MPA for “violent content, bloody images, some language, and suggestive material.”
