A group of friends, including Mitch, Gilbert, Kylie, Chanda, Jonah, and Ronnie, go to the beach for a party. However, their fun is disrupted by a mysterious creature that lives under the sand. The creature starts to attack them, and they soon discover that it is a massive, tentacled monster that can eat anything that touches the sand.
As the group tries to escape, they realize that the monster is attracted to noise and movement, and that it can be repelled by hot surfaces and certain materials. They use this knowledge to try and outsmart the creature, but it proves to be a formidable foe.
One by one, the group members are picked off by the monster, until only Kylie and Chanda are left. They manage to escape by using a piece of metal as a bridge and setting the monster on fire with gasoline.
In the end, Kylie and Chanda escape the beach, but not before they see that the monster is still alive and has survived the fire. The movie ends with the monster attacking another beach, leaving the audience with a sense of dread and uncertainty.
