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. In the meantime, Sanada continues treating his other patients, one of whom, a young female student, seems to be making progress against her tuberculosis.
