University student Mamiko invites classmates Jason, Freddy and Regan over for an impromptu pizza party. When their discussion turns to horror films, the group finds itself at an impasse over what defines horror: American violent or Japanese atmospheric. Seeking to prove the Japanese brand of horror the creepier of the two, Mamiko leads her friends to a nearby field said to be the resting place of Misaru, the slain daughter of a shamed samurai. Although successful in resurrecting Misaru's spirit, the group's expectation of a docile, feet shuffling ghost girl couldn't be more off the mark - as the evening turns into a fight for survival!
