In the desolate landscapes of Yucca Flats, Nevada, a nuclear experiment turns into a literal nightmare. Dr. Eric Zinthrop, a scientist who has been working on a project related to atomic energy, finds himself in the midst of a nuclear test when an unexpected accident transforms him into a nightmare creature. Disfigured and stripped of his humanity, he becomes a monster that roams the desert, leaving a trail of chaos and death in his wake.
Meanwhile, a group of tourists ventures into the area, unaware of the threat looming over them. The authorities, stunned and unsure of how to handle the situation, try to contain it, but the creature is unstoppable. Tension escalates as encounters between the monstrous creation and the unsuspecting tourists become increasingly dangerous. As night falls, the characters find themselves trapped in a desperate struggle for survival, facing not only the beast but also the rising paranoia and fear brought on by radiation.
With a touch of social commentary on the consequences of nuclear experiments, the plot unfolds in a horror and science fiction setting, where the line between humanity and monstrosity completely blurs. In this apocalyptic scenario, the fight for life becomes a game of instinct and survival without limits.
