Door Gagan Ki Chhaon Men (1964)
Shankar (Kishore) returns from war to find his house ravaged and wife perishing in the fire. The traumatised son Ramu (Amit Ganguly) survives but loses his voice from the shock. There is kind-hearted woman (Supriya Chaudhary) who develops a motherly affection for Ramu.
Shankar leaves no stone unturned as he prays and pleads for his son's voice, seeking the best of doctors and divine help. "Bapu" (father) is all he craves to hear. He confronts a scheming village tyrant and wages a lonely battle that he wins after much suffering. It, however, appears odd that the tyrant gets away with all his scheming so conveniently in a village that proudly looks up to a war hero for protection. In the end, good prevails over evil, the son regains his voice.
