Seven American high school seniors, all close friends since childhood, organize a trip to explore an abandoned nuclear power plant. Inside, they touche unstable equipment, triggering a gas explosion and toxic leak. They escape the nuclear base, apparently, in good conditions. But long after in the day, they suffer violent sickness: vomiting, seizures, sweating, hallucinations. Days later, they awaken with powers. They promise themselve to become heroes and stop the evil, but no one could predict that the evil might be in one of them...

Seven former Marines bound by an unbreakable friendship are catapulted into a deadly game orchestrated by invisible and powerful creators on a remote island. The island hosts 32 groups of people forced to clash with each other. The goal is clear: in the end, only one group will remain alive and will be able to obtain a prize that will erase the past and offer a new life far from the mistakes made. The seven face extreme challenges and deadly combat, gradually transforming into ruthless and determined figures. As the island crumbles piece by piece and the game grows increasingly cruel, no one is safe, and each step towards victory brings the darkness within them ever closer.
