The story revolves around a group of teenagers who visit a beach for a party, unaware that the beach is closed due to water pollution. They discover a strange object in the sand, which hatches a creature that can kill by sucking people into the sand. As the group tries to survive, they realize that the creature is attracted to human skin and can be deterred by leather shoes or towels.
One by one, the group members fall victim to the creature, and the survivors try to find ways to escape. They eventually discover that the lifeguards who visit the beach are immune to the creature because they wear leather shoes.
In the end, only two members of the group, Kaili and Anda, survive by using a lifeboat to escape the beach. However, Zone, who was injured by the creature, dies in the car. The film ends with Kaili and Anda safely escaping the beach, while the creature continues to thrive in the polluted water.
