Watch on Soap2day. After years without seeing each other, Tsumugi goes camping with her former track and field teammates. Their excitement at the reunion fades when a conflict they were never able to resolve resurfaces. What no one can imagine is that they're sleeping on the site of an ancient execution ground, where centuries ago villagers were crucified naked. At night, their spirits emerge to hunt down the campers. And then Tsumugi discovers the only way to survive: by undressing.
