Tohfa (1984)
Janaki (Jayaprada) and Lalita (Sridevi) are sisters who love each other dearly. Lalita and Ram (Jeetendra) fall passionately in love with each other. Unknown to them, Janaki is also in love with Ram. When Lalita finds out, she decides to sacrifice her relationship with Ram. In haste, she marries a good-for-nothing man (Shakti Kapoor), who is arrested by the police immediately afterward. Unaware of Lalita’s true motive, Ram and Janaki are furious with her.
Lalita moves away and is not seen for several years. Ram and Janaki get married and live happily; their only sorrow is their inability to have children. Many years later, Ram meets Lalita again. She is working in an office and singlehandedly bringing up her son. To his shock, Ram realizes that he is the father of Lalita’s son.
