A breathtaking tropical adventure quickly descends into a fight for survival in The Devil’s Mouth, an upcoming horror-thriller set to premiere on Prime Video on July 29, 2026.
Directed by Jeff Wadlow, the film blends suspense, underwater thrills, and emotional character dynamics into an immersive survival story. It stars a rising ensemble cast led by Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno, Tommi Rose, and Tayme Thapthimthong, portraying a group of recent college graduates whose carefree summer getaway turns into a terrifying nightmare.
Set against the breathtaking coastal caves of Thailand, The Devil’s Mouth transforms a natural wonder into a claustrophobic maze where danger lurks around every corner. The stunning location provides the backdrop for a relentless fight for survival beneath the surface.
The story follows five friends who embark on one last adventure before stepping into adulthood. Looking to make the most of their final days together, they sign up for a guided swim through a remote cave system known as The Devil’s Mouth.
Their thrilling excursion soon spirals into horror when they discover that a freak storm had flooded the caves with sea life. While most of the creatures perished in the fresh water, something else survived—and it is now hunting them. Fast, silent, and deadly, the mysterious predator turns every narrow passage and every wrong turn into a life-or-death encounter.
As panic spreads and escape becomes increasingly difficult, the group’s friendships begin to fracture. Trust erodes, fear takes over, and survival demands impossible choices. Trapped in the suffocating darkness, they soon realize that making it out alive may require heartbreaking sacrifices.
Featuring a charismatic young cast, The Devil’s Mouth balances moments of humor and camaraderie with escalating tension, making the emotional stakes just as compelling as its terrifying underwater encounters. With its unique setting, pulse-pounding suspense, and creature-driven horror, the film promises a gripping survival experience for genre fans.
The Devil’s Mouth begins streaming exclusively on Prime Video on July 29, 2026.
