Embedded with fiery action and scintillating suspense, this family-oriented drama delves into the twists and turns in the life of Hareendran (Mammootty), a kind-hearted man, with a tough exterior. He is a struggling small time contractor.
Shekhara Menon (Thilakan) is a retired income tax officer from Mumbai and has now settled in a remote village in Kerala. He owns some land and a house where he and his three daughters live together and leads a peaceful, content and happy life. Menon owns a smaller house adjacent to his own which is given for rent, and his source of income other that agricultural income. Mr. Menon's Pension from service has been blocked due to some unclear issues.
Hareendran (Mammootty) moves in as the new tenant into Mr Menon's rented house. He is constantly put under unwanted troubles by his aide Balachandran (Sudheesh), who convinces Hareendran to help people in trouble. His experience with Balachandran has made Hareendran a selfish man and he presently is least concerned about other peoples problems around him.
However, his tough exterior melts after Menon goes absconding leaving, his three daughters alone in the house. Hareendran, the selfish tenant quickly decides to vacate the house to avoid unwanted troubles.
Even though he is seemingly selfish and unkind, the good hearted Hareendran cannot stand the harsh difficulties forced to be faced by the girls in front of his house. The crux of this evocative tale delves into how only Hareendran (Oral Mathram -> the only person) steps up to help the girls, but the question remains, will he be able to ascertain what happened to Mr Menon and bring him back to his family?
