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.

Jared Richards The Age (Australia) 1d
2/5
The devil’s in the details, which this bland horror largely lacks – especially in its muddy underwater scenes, ugly in all the wrong ways. Go to Full Review Peter Gray The AU Review 11h
2.5/5
While it never quite escapes the formula that’s defined this particular corner of creature-feature cinema for decades, it delivers just enough tension to make the ride worthwhile. Go to Full Review Read all reviews
