is a 1948 Japanese yakuza film directed by Akira Kurosawa. It is notable for being the first of sixteen film collaborations between director Kurosawa and actor Toshiro Mifune. Plot Sanada (Takashi Shimura) is an alcoholic doctor (the titular "drunken angel") in postwar Japan who treats a small-time yakuza named Matsunaga (Toshiro Mifune) after a gunfight with a rival syndicate. The doctor, noticing that Matsunaga is coughing, diagnoses the young gangster with tuberculosis. After frequently pestering Matsunaga, who refuses to deal with his illness, about the need to start taking care of himself, the gangster finally agrees to quit boozing and womanizing and allow Sanada to care for him. The two enjoy an uneasy friendship until Matsunaga's sworn brother, Okada, who is also the abusive ex-boyfriend of the doctor's female assistant Miyo, is released from prison.

There, he finds his sworn brother with Nanae, Matsunaga's former sweetheart who abandoned him due to his failing health, and angrily tries to stab him before starting to cough up blood. Okada then stabs him in the chest, and Matsunaga stumbles outside before dying of his wounds. Okada is arrested for the murder, but Matsunaga's boss refuses to pay for his funeral.
