Gopikrishnan, an ex-military, has dedicated his life to looking after Vellimala Dam. Koshy Ommen comes to Vellimala to find a way out to the monetary problems created by his father, who undertook the contract connected with the dam project. The death of his father made him bankrupt and he wanted to get his money back. But the payment of the bill was being withheld by Varghese, a candid and honest Engineer, alleging irregularities in the project. Koshy Ommen must stay back at the dam site to get the bill passed by Varghese, who cannot be easily convinced or tempted.
