Kathryn Newton reunites with Radio Silence after her terrifying experience in "Ready or Not 2" to head to Thailand for a new thriller titled "The Devil's Mouth." This film revolves around five friends on their last summer adventure, which unexpectedly turns into a horrifying ordeal. Premiering on Prime Video later this month, the film showcases the group's journey filled with dangerous events.

The promotional poster highlights the chilling entrance of "The Devil's Mouth." This entrance resembles an open jaw, creating a trap ready to swallow those who enter. Newton stands out alongside Lana Condor, the star of the "To All the Boys" series, as they embark on this adventure with their friends Nico Hiraga, Gavin Casalegno, and Tommi Rose. However, unaware of the danger ahead, they venture into narrow, winding cave corridors. "The Devil's Mouth" offers a classic shark survival thriller; yet, the group struggles in a confined cave area with the shark instead of the open sea.

A major storm that occurred a week before the friends' guided swimming tour in the caves had swept marine life into the cave's freshwater. This situation heightens the terrifying atmosphere of "The Devil's Mouth," making the encounter with a surviving shark in a setting meant for relaxation even more horrifying. This silent, deadly, and hungry shark waits for them with every wrong turn or slip. The film follows the group's survival instincts coming to the forefront as they begin to get lost in the dark corridors, with sacrifice becoming their only hope.

In conclusion, "The Devil's Mouth" offers thrilling moments while showcasing the characters' struggle for survival. This film stands out as a must-see for both horror and adventure enthusiasts.
