He is still young, the actor who should become known around the world with masterpieces like "Rashomon" or "The Seven Samurai". Here, Akira Kurosawa has created a thriller against the background of the recent and completely unprocessed Japanese war past, of which many of the characters, whether woman or man, talk. "Stray Dog" plays during the sultry hot summer in Tokyo in 1949. The young and completely inexperienced inspector Murakami (Toshiro Mifune) gets his loaded service weapon stolen from his jacket pocket in an overcrowded bus. Murakami is beside himself. He fears the worst consequences for his still young career. Together with his older colleague Sato from the theft department, he sets out on a search for traces of the thief. While we roam about the Japanese post-war setting with him, he gains experiences and learns to keep calm from the old and experienced colleague Sato. Women who are involved in what is going on are also snarling at him as a greenhorn. An impressive milieu study by Akira Kurosawa, in which the master proves himself in the genre film and shows us what he is capable of in narrative, atmospheric and visual terms.
