Kundanlal was murdered and his wife and child vanished on a dark night- at the haunted bungalow surrounded by a jungle in the outskirts of Bombay.
Fifty years later- three brothers who are nephews of Kundanlal are presently living in the Bungalow- they are Shyamlal (Nasir Hussain), Ramlal(Nana Palsikar) and Dhamu (Asit Sen). On the eve of Rekha (Tanuja)- Ramlal's daughter's return from London- Ramlal is killed in a car accident which is suspected as murder and the suspicion is reinforced when on the same night- Dhamu is found hanging in his bedroom, although postmortem reports claim he was murdered before being hanged.
Shyamlal and Rekha move out of the Bungalow to their home in the city and live there- however Rekha receives strange phone calls - threatening her with death. She meets Mohan Kumar (Mehmood) who is 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. Rekha and Mohan soon fall in love with each other.
The climax takes place in the Bungalow when the murderer is revealed to be Kundanlal's child who vanished into the night with his mother- now the family doctor of Shyamlal and his family. His mother- Kundanlal's wife who vanished into the night- tells the group that Kundanlal's elder brother- Shyamlal's father- was the one who murdered Kundanlal owing to which her child was avenging his father's death.
