Directed by Jeff Wadlow, the film stars Kathryn Newton as Sara and Lana Condor as Max.
The narrative follows five vacationing friends who venture into a remote freshwater cave network with their tour guide, Wat, played by Tayme Thapthimthong.
Tensions escalate after recent monsoon storms force sea life into the freshwater caves through an oceanic wall opening.
The group becomes trapped inside narrow passages alongside an aggressive bull shark, a species capable of surviving in both salt and fresh water.
As panic spreads through the submerged caverns, long-buried emotional fractures begin to unravel the friendship between Sara and Max.
Their fight for survival transforms into a struggle over leadership and dynamic dominance.
Director Wadlow noted that the core emotional anchor is the evolving dynamic between the two lead characters rather than just the creature terror.
"I was told it's a shark movie in a cave... and I was like, well, I'm in," said Wadlow.
Wadlow emphasized that the complex friendship in the original Black List screenplay by Aja Gabel and Myung Joh Wesner provided a unique perspective for the horror subgenre.
"But then I read the script, and there was this really nuanced, complex female friendship at its core.
