Mera Saaya

Thakur Rakesh Singh (Sunil Dutt), an affluent descendent of the royalty, is a lawyer and happily married to Geeta (Sadhana) for three years. He goes to London for higher studies and after one year receives the news of his wifes illness. He immediately comes back only to witness his wifes death in his hands. He builds a small memorial in her memory in his mansion. He deeply mourns her by always sitting at that memorial and listening to recorded songs sung by Geeta.

While things are like this, one day a police inspector Daljit comes to meet him. He explains him about the bandit they caught on other day, Naina (Sadhana) who claims to be wife of Rakesh. Rakesh meets her and gets shocked as she looks exactly like Geeta. But he rejects that she was his wife as he saw his wife dying and buried her with his own hands. But that woman claims that she was indeed Geeta and tells him about intimate moments they shared.

Rakesh gets surprised but suspects some mischief.Case proceeds in the court and Rakesh starts to cross examine that woman. She answers every question correctly and claims that she was kidnapped by someone 2 3 days before her arrest. When Rakesh asks why she has no mangalsutra on her, which was compulsory ornament for married Hindu woman, she tells him that she removed it before going out on that day. He wouldnt believe that, as Geeta would consider mangalsutra very sacred and wouldnt have removed it.

After some drama, he asks her about her diary which Geeta always keeps near to her and she fails to answer. He decides that she was just an impostor and asks court to convict her. She becomes emotionally unstable after all this drama and ends up in a mental institute. One night she escapes from there and comes to Rakeshs house. There she explains Rakesh all that has happened.

Geeta had a twin sister named Raina, who was a bandit just like their mother. Geeta hides the fact about her criminal family and marries Rakesh. But one day her sister comes to her in a pitiable condition and asks her to give shelter for one night. Geeta, seeing her sick gets out of her house to buy medicine. But she doesnt want other family members to know about Raina and makes Raina up just like her and even gives her own mangalsutra to Raina.

But when she comes out, Ranjit singh,Rainas husband (Prem Chopra)mistakes her for Raina and takes her away without giving her chance to talk. When Ranjit Singh comes to know that she wasnt Raina, he wants to take her back but police arrest them on their way back. While she was explaining all this to Rakesh, Ranjit Singh comes there and confirms her story. Police shoot him and he dies at Rainas memorial. Rakesh and Geeta reconcile and start their regular life.
