Anu Anand

Dr. Balasubramaniam (Mohanlal), after his wife Rukmini's (Urvashi) death, devotes his life for raising son Raju Vishwam (Anu Anand), disregarding even his best friend Mani Sankar Iyer's (Nedumudi Venu) sister & coworker Sreelakshmi's (Parvathi) feelings towards him. When Raju goes to college, Balasubramaniam rejoices, but his joys are cut short when Raju dies in a hazing incident in college at the hands of his seniors. The law lets the culprits go free, but Balasubramaniam doesn't forgive them.

Vishwanathan (Mammootty) & Janani (Suhasini) fall in love in college & get married, even after Janani's father, famous singer & college principal Ragam Vaidya Nathan (Adoor Bhasi), opposes their relationship. However, later when Vishwanathan becomes a great singer & Janani becomes a renowned dancer, their egos clash, causing Vishwanathan to walk out with their infant. 8 years later, on the verge of Janani being awarded the prestigious 'Natya Sri' award, Vishwanathan returns, for revenge.
