A former gang leader and lone wolf who has left the organization works behind the scenes in a new city to take revenge on a giant alliance of organizations. This film is amongst the last "straight" yakuza films made at Nikkatsu before the studio's switch-over to pinku eiga.
Unfortunately the movie The Killer is not yet available on HBO Max.
