A pair of hard-boiled Tokyo cops are investigating a gruesome murder: after killing the victim, the murderer cut his skull open and cooked his brain in a stew. As they try to track down the killer, they discover that, quite literally, everybody is a suspect. Will they bring the terror to an end, or will they become part of it themselves?
