"Ruler" is made to rule the world, and they haven't gave up since their first massacre 2 years ago. "The Box" was made by the government to tackle "Ruler" down. Tania, Arga, and Jonas were just in highschool, studying for college. But that changes when Marina, a member of "Ruler" locks them all and forces the students to play Death or Favor, a game where if you manage to do all the favors given, you survive and if not, you die. Unfortunately, only the three of them survived and were separated.
