Directed by Akira Kurosawa and starring Toshiro Mifune and Takashi Shimura, the plot revolves around a rookie cop who has his gun swiped on a trolley in Tokyo. The young man is obsessive about getting his weapon back and after reporting the missing gun, he walks the streets looking for answers. His searching leads to a gun racket and after a crime is committed the rookie partners with an old vet on the case. They eventually wind up at a baseball game and begin searching for a man named Yusa. Another crime is committed and now the pair question a reluctant show girl. The older Sato follows the trail of Yusa and meets with trouble. Finally, the girl talks and the desperate rookie searches for the mysterious Yusa. In their final showdown he rights everything and retrieves his gun. I found this film-noir very atmospheric with post-war Tokyo and heat and humidity that you can almost feel. The two main characters have a solid chemistry because only together can they catch the Stray Dog.
