Olangal (1982)

Life goes on happily for the couple, Ravi (Amol Palekar) and Radha (Poornima) who live with their only daughter until Father John arrives in the city with a young boy Raju, Ravi's son from an affair with Reetha (Ambika) before his marriage to Radha. Now he has to keep the boy with him for a month before Father John takes the boy abroad.

Ravi introduces the boy to his wife as the son of a dead friend, George, and she happily accepts to keep the boy with them. But the truth emerges when the 'dead friend' visits their house. The six-year-long marriage between Ravi and Radha shatters.
