The Devil's Mouth

 Five friends set out on one last adventure along Thailand’s stunning coast, eager for a fi nal 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 fl ooded 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 overfl owing 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, sacrifi ces must be made.
