The film begins with Kadhirvel (Prashanth), a do-gooder going all out to get water for his village. With monsoon repeatedly failing, his village reels under drought and Prashanth runs from pillar to post to get a well dug in the village. He manages to bring Shanmugham (Mahadevan), a water-divining expert to dig a well in the village. Shanmugham along with his wife and daughter Marikozhundhu (Pooja) come to the village. Unfortunately a freak mishap kills Shanmugham and the villagers' search for water continues.
