A group of very different people wake up together in the sealed
environment of an abandoned school building. They include the college
students Yumi and Reiji, a cabaret girl named Akane, an occult-obsessed
salaryman named Yukitoshi, a punk factory worker named Toshio, an
unemployed pedophile named Taichi, and a 9-year-old girl named Michika.
The building in which they find themselves has running water, no food,
and a timer set for seven days. When they find a cleaver and a hot pot
in an upstairs classroom, they begin to guess the intention behind their
imprisonment; they're meant to kill and eat one another to survive. In
principle, they should be able to survive just by waiting out the seven
days in hunger, but nothing is ever that simple...
