The Guard from Underground

An ex sumo wrestler turned corporate security guard, Fujimaru (Yutaka Matsushige), goes on a murderous rampage at his place of employment after finding an earring lost by Akiko Narushima (Makiko Kuno). Trapped in the building with her and trying to stay alive, are Akiko's co-workers. Eventually, Fujimaru traps Akiko in the office of eccentric Mr. Hyodo (Hatsunori Hasegawa), who is later safely taken out of the building by police.
