After that nothing remains the same for anyone – everything changes – Nisha develops a dark, obsessive love for Sanjay after a night of love making.
Sanjay takes that night as a one night stand when Trisha has gone to Paris. But Nisha is not willing to let him go. She tries her best to win over Sanjay but Sanjay is not interested.
Her craving for him becomes obsessive and pathological. She begins to show her true colors. She gets psychotic. She has also committed a murder in the past!

The pressure keeps mounting. Sanjay finds himself in a no win situation. On one hand is the certainty of losing Trisha if she finds out the truth about Nisha. And on the other, Nisha's threat to kill Trisha is chillingly real! Life has becomes hell for Sanjay.
Then as suddenly as Nisha had entered Sanjay's life, a shadow from her ugly past returns to haunt Nisha – Harsh (Sameer Dharmadhikari)!

As the tension rises for Nisha, she terrorises Sanjay more mercilessly – his mind, his nerves are at breaking point. It is time he took drastic steps. He is on fire and will kill to rid his life of Nisha's evil being and Harsh's sadistic presence.
Sanjay must get his life back, his love back – but will he be able to? This and all other questions will be answered by Sultaan Productions – Husn - Love and Betrayal!
