Pinku from 1966.

Aspiring to an easy job as personal physician to a wealthy family, Noboru Yasumoto is disappointed when his first post after medical school takes him to a small country clinic under the gruff doctor Red Beard. Yasumoto rebels in numerous ways, but Red Beard proves a wise and patient teacher. He gradually introduces his student to the unglamorous side of the profession, ultimately assigning him to care for a prostitute rescued from a local brothel.
