Strange Occurrences: In a small Texas town, a series of strange events and unexplained disappearances occur. People and livestock are vanishing without a trace, and their vehicles are left abandoned.
Local Teens Investigate: A group of local teenagers, including the film's protagonist, Chase Winstead (played by Don Sullivan), and his friends, become concerned about the disappearances. They begin to investigate the strange occurrences and search for clues.
Discovery of a Giant Gila Monster: As they explore the area, the teenagers discover that the cause of the problems is a massive Gila monster, a type of venomous lizard, that has grown to an enormous size due to exposure to radiation. The giant creature is responsible for the disappearances and is a menace to the community.
Community Response: The town's sheriff and other adults are initially skeptical of the teenagers' claims about the giant lizard. However, as more evidence of the monster's existence emerges, the community bands together to stop the creature and protect their town.
Showdown: The film culminates in a showdown between the teenagers, local law enforcement, and the giant Gila monster. They devise a plan to trap and confront the creature, leading to a climactic battle to rid the town of this menacing reptile (1959).
