Pyasa Shaitan (1984)

Shaitan (Joginder) needs to sacrifice seven young women so that he can attain immortality. He stumbles upon a man (Kamal Hassan), who had been worshiping Satan himself for many-many years. The man has grown old and also wishes to stay young forever. Shaitan signs a deal with him, granting temporary youth at first, that will become eternal after the sacrifice of the 7th and last young woman.
