THE DEVIL'S MOUTH Cast Made a Splash at Obsessed Fest in Los Angeles This Weekend

Blending suspense, underwater thrills, and emotional character dynamics, The Devil's Mouth delivers an immersive survival experience and fun summer adventure.

Featuring a rising young adult ensemble cast including Kathryn Newton, Lana Condor, Nico Hiraga, Gavin Casalegno and Tommi Rose, the film captures the humor and energy of college grads before plunging audiences into a fight for survival.

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.

Synopsis

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.
