Six former high school classmates are kidnapped by a mysterious force because of a dark secret they share, then thrust into a meticulously designed game of “humanity’s apocalypse.” Forced to struggle for survival amid suspicion, alliances, and betrayal, they know that every choice could get a companion killed. The game pushes human emotions to their limits. Only by squeezing the last drops of selfishness and survival instinct from their souls can it create a single “perfect survivor.”
