The film was dubbed into Telugu as Mouna Geetham.

Chandrasekhar (Sarath Babu) is married to Mala (Shanti Williams) and their marital life is miserable due to Mala's demonic behaviour. Chandrasekhar's sister Viji (Suhasini), who is brought up by him, is enthusiastic, naughty and fun-loving. She lives life on her own terms. One day she bumps into Ram (Mohan), a mechanic. Despite initial conflicts, they slowly become friends. Though good natured, Ram suffers from an inferiority complex and suspects everyone. Mala suspects that Chandrasekhar's classmate Ramya (Vanitha) is his concubine since he visits her often. Chandrasekhar learns of Ramya's love for him only after his marriage to Mala. Ramya remains single and they share a platonic relationship, which antagonises Mala. Pratap (Pratap K. Pothen) is a photographer and a distant relative of Chandrasekhar. He comes to Chennai from Calcutta and works for an agency. Though Pratap likes Viji, he does not propose to her.
