Chandrasekhar (Sarath Babu) is married to Mala (Santhakumari) 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.
