Hell Dogs

Inside a yakuza organization, a former police officer named Shogo Kanetaka (Junichi Okada) has come in under a false face, driven by revenge. His way in is Tsutomu Toki (Kazuki Kitamura), one of the group's most unhinged members, and Shogo has to win the man's friendship. Masato Harada keeps Shogo close to his plan as he gets near enough to a dangerous man that he can no longer step back.
