Maayi (Sarathkumar) is the well-respected, do-gooder in the village. He sees women in the village as his sisters and even conducts their marriages. He is a man who is ready to kill his father(Vijayakumar) when he learns that he had a second wife. But the father opts to kill himself rather than face his son and so, Maayi brings his stepsister Lakshmi (Suvalakshmi) to live with him. When the local MLA(Rajan. P. Dev) comes to him for support, he refuses and the MLA loses the election. But his son(Anand), who admires Maayi, marries Lakshmi.
Meanwhile Bhuvaneswari (Meena), Maayi's sister's daughter comes to the village from Bangalore and she initially misunderstands Maayi by seeing his looks but later realizes her mistake after knowing about Maayi's hard work and his help towards improving the village. Maayi has built free hospital, day care center, college etc to help the villagers. Bhuvaneshwari is attracted towards Maayi and proposes him but Maayi does not accept his love. He tells his flashback. Maayi was born into a a very poor family where his mother (Sabitha Anand) was infected by leprosy even before Maayi's birth. Due to poor financial condition, his mother could not be treated in hospital and instead was kept alone in a room. She was not allowed to touch her son Maayi fearing chances of being spread. One day, Maayi's mother gets frustated as she can't even touch her child because of leprosy and she commits suicide. This shocks Maayi and he decides not to marry any woman as he does not want any girl to touch his body which was even untouched by his beloved mother.
Maayi convinces Bhuvaneshwari to marry someone else. Also, Maayi comes to know that his step sister Lakshmi is being tortured by her husband and it was all a plan to take revenge on Maayi for not supportnig the local MLA during elections. Maayi beats up Lakshmi's husband and says that he will never support criminal activities even if it impacts his family. On the day of Bhuvaneshwari's wedding, the bride groom's family misunderstands that Maayi and Bhuvaneshwari are lovers seeing Maayi's dhoti in her room and stops the marriage. Bhuvaneshwari's friend discloses the truth that Maayi gave his dhoti to safeguard her when her dresses were washed away in water sometime back. Manorama who also belongs the village shouts at the groom's family for their cruel thoughts and she requests Maayi to marry Bhuvaneshwari as that would be the right thing. Maayi obeys Manorama's words as his mother's and marries Bhuvaneshwari.
