She cannot bring herself to forget Vishwa (Mammootty), a man she has been in love with for two decades. Memories of Vishwa haunt her constantly, and upon a chance meeting with him, she discovers he too is struggling with his love for her. Both are haunted by the memory of Thulasi’s cousin, a figure who is unable to control his obsession for his cousin and hide his resentment at Thulasi’s feelings for Vishwa. Thulasi (Nandita) comes to Sundarapuri after her guardians – her grandma and uncle – pass away, to work as teacher in a dance school. It is in Sundarapuri that Vishwa (Mammootty) the zamindar whom she had met 20 years ago, lives. They meet again and the feelings that had blossomed in their hearts as teenagers, are revived.

It is then that Fate enters in the form of Siva (Manoj K. Jayan).
