Uttoran (1994)

Sen Gupta, a doctor who only treats upper-class patients, is forced to confront his own moral and medical beliefs as he discovers rural India during an unexpected stop at a village. He finds a breathless man lying on the side of the road. With little sympathy, the doctor sends him back to his own village for treatment. When Dr. Gupta discovers that the villages want a witch doctor to treat the man, he attends the exorcism and is shocked. A transformation of the cold city man then follows.
