Part of a collection of Japanese noir films, Rusty Knife (1958) packs a punch. A relentless D.A. won’t give up on getting justice for a murder that was wrongly categorized as a suicide. He hunts down two reformed gangsters, who witnessed the murder as other yakuza (Japanese mobsters) killed a city official. One of the witnesses now owns a bar and has turned over a new leaf. However, the guilty and anger towards these gangsters who brutally raped and murdered his true love. As the D.A. urges him, the reformed gangster pursues the yakuza and seeks revenge.
The emotions run high and the plot has some great fight scenes. The plot offers plenty of surprises. I recommend this film and would certainly watch more of director Toshio Masuda’s films.
