Fifty years ago, Kundanlal was murdered and his wife and child vanished at the haunted bungalow surrounded by a jungle in the outskirts of Bombay. In the present, three brothers are living in the bungalow, who are Kundanlal's nephews. They are Shyamlal (Nazir Hussain), Ramlal (Nana Palsikar) and Ramu. On the eve of Ramlal's daughter, Rekha's (Tanuja) return from London, Ramlal is killed in a car accident which is suspected as murder. The suspicion is reinforced when Ramu is found hanging in his bedroom on the same night. Postmortem reports claim he was murdered before being hanged. Shyamlal and Rekha move out of the bungalow to their home in the city. However Rekha receives threatening phone calls about her death. She meets Mohan Kumar (Mehmood), the president of a local youth club, when he defeats her in a music competition. She soon confides to Mohan about the phone calls and Mohan begins to investigate into the calls. Will they find out what happened?
