The Devil’s Mouth, an upcoming survival horror thriller, will premiere on July 29 on Prime Video.
The film follows a group of college friends, who get trapped inside a flooded underwater cave system alongside a deadly predator while on vacation in Thailand. Blending suspense, underwater thrills and emotional character dynamics, the film delivers an immersive survival experience and fun summer adventure.
It follows five friends who 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.
Set against the stunning backdrop of Thailand’s coastal caves, the film transforms a natural wonder into a claustrophobic nightmare where danger awaits around every corner. The film was shot across various provinces in Thailand, including Bangkok, Krabi, Mae Hong Son and Samut Prakan. Thai actor Tayme Thapthimthong also stars as a local cave guide.
Featuring a rising young adult ensemble cast including Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno and Tommi Rose, the film captures the humour and energy of college grads before plunging audiences into a fight for survival.
The film is already giving the same vibes as the 18-day, international operation in 2018 where 12 boys and their 25-year-old soccer coach were saved from the flooded Tham Luang cave in Chiang Rai province.
