 Radha (Suchitra Sen), a nurse at a mental hospital, is asked by the head doctor (Pahari Sanyal) to try an experimental technique with a somewhat amnesiac, depressed inmate (Vasant Choudhury) - she has to pretend to be in love with him to bring him back to normal. Remade in Hindi as Khamoshi with Waheeda Rehman playing the Suchitra Sen character, this film still stands the test of time. Performances are good.
