Chirag(1969)

Synopsis

When Ajay (Sunil Dutt) meets Asha (Asha Parekh), he mistakenly believes she's wealthy. The fact that she's not, however, doesn't prevent him from becoming smitten, and the couple soon marries with the full blessings of Ajay's family. Poverty is one thing, though, and childlessness quite another -- which Asha finds out the hard way. When she fails to produce an heir for the clan posthaste, her mother-in-law begins a search for her replacement.
