Prime Video has released the official trailer for The Devil's Mouth, an intense new survival thriller premiering globally on July 29. Directed by Jeff Wadlow, the film stars Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno, Tommi Rose, and Tayme Thapthimthong.

Blending suspense, underwater thrills, and emotional character dynamics, The Devil's Mouth follows five recent college graduates who set out on one last adventure along Thailand's breathtaking coastline before beginning the next chapter of their lives. Their trip takes a terrifying turn after they join a guided swim through a remote cave system known as The Devil's Mouth, only to discover they're no longer alone beneath the surface.

After a freak storm floods the caves with seawater, a deadly predator becomes trapped within the labyrinth of narrow waterways. As the friends struggle to find a way out, dwindling hope, mounting fear, and fractured relationships become nearly as dangerous as the creature stalking them through the darkness.

The trailer showcases a tense blend of claustrophobic cave exploration, nerve-racking underwater sequences, and pulse-pounding encounters that promise a suspenseful survival experience. Set against the stunning backdrop of Thailand's coastal caves, the film transforms a natural wonder into a deadly maze where every decision could mean the difference between life and death.

Based on this first look, The Devil's Mouth appears to offer a fresh take on the survival thriller by combining the tension of underwater cave exploration with the relentless threat of a deadly predator. If it delivers on the suspense teased in the trailer, it could become one of Prime Video's standout genre releases of the summer.

The Devil's Mouth premieres July 29, exclusively on Prime Video.
