Trailer: 

Deep in the remote wilderness, an elite team of researchers embarks on an expedition to study a mysterious underground lake that has remained untouched for centuries. Led by marine biologist Dr. Evelyn Carter, the team hopes to uncover ancient secrets hidden beneath the water’s surface. But as they descend deeper into the cavernous abyss, something watches them from the darkness.

At first, the expedition seems like a scientific breakthrough—strange new species, uncharted depths, and eerie echoes that hint at a larger ecosystem. But when one of their crew mysteriously vanishes, fear creeps in. Equipment begins to fail, communication with the outside world is cut off, and an unsettling realization dawns: they are not alone.

Tensions rise as the team struggles to navigate the suffocating darkness, each step leading them closer to the horrifying truth of what lurks beneath. The deeper they go, the more they uncover a terrifying reality—this lake is not a relic of the past; it is a hunting ground. And they have become the prey.

With chilling suspense, pulse-pounding action, and claustrophobic dread, What Lurks Beneath plunges viewers into an abyss of terror, where survival is not guaranteed and the unknown is far more dangerous than they ever imagined.
