M. Sasikumar, Varalaxmi Sarathkumar
Sannasi (M. Sasikumar) is a multi-talented folk dancer and nadaswaram expert in a village living with his father Samipulavan (G. M. Kumar). Samipulavan was once a great singer and thavil expert who stopped performing singing and playing thavil because of the indecent content in the folk dances by the younger generation in recent years. He also has stopped talking with his son because of the same reason.Sooravalli (Varalaxmi Sarathkumar) is Sannasi's aunty's daughter who loves Sannasi very much and expresses her love often for which Sannasi doesn't responds.Both Sooravalli and Sannasi are in the same group of dancers who go to places for performing.
An innocently dressed Karuppaiah (R. K. Suresh) often interrupts the male performers in the group wherever they go , to know where the next dance programme would happen. One day Sannasi gets a phone call from a group of men in a lodge near by. They pay him a lumpsum amount to book his group for a dance programme in a temple in Andaman Nicobar islands. The group goes to Andaman by a passenger ship , stays in the hotel provided by the organizers and performs Karagattam in a temple. The men who organized the dance liked the women dancers and asks Sannasi to show them the girls indirectly asking for sex. Sannasi without uttering any word takes the organizers to the room where the lady dancers are staying and says to them that he has showed the girls as per their wish . Sooravalli who is short tempered fiercefully hits all the organizers knowing that they had asked for sex with the lady dancers including her. The organizers who were drunk at that time were badly injured and in turn they tore the return tickets to main land India taking revenge on them. That night the group of dancers could not find a shelter and sleeps in the road. Not knowing how to get back to main land India, they go in search of a job. A building contractor helps them to find a construction work and asks for some percent of money as his commission. Agreed to this the group of dancers work in the construction site only to damage the buildings and the constructions built so far. In the chaos Sooravalli gets hurt by getting her feet pricked by a nail. The building owner gets irritated with the damage and scolds the contractor. The contractor asks them to stop the work and go back. Without any money the dance group was not able to buy even a tea. Soorvalli who could not see Sannasi starving for hunger puts her make-up and dances karagattam in the street asking the thavil players and nadaswaram players to accompany her. Mesmerized by the dance the public gives them enough money with which they return to mainland India. While returning Sooravalli fells ills because of the nail which got pricked in her foot. Sannasi takes care of her through out the journey which improves their bonding.
One day Karuppaiah takes Sannasi to a hotel and begs him to get married to Sooravalli saying that he likes her very much. Sannasi who just returned from Andaman after a bad experience hits Karuppaiah in the public . Karuppaiah escapes and after a few days meets Sooravallis mother. He convinces her to accept his wish and says her that he works as a driver for the district collector. Sooravalli's mother speaks with Sannasi and forces him to hate Sooravalli. Sannasi drinks liquor for the first time and then forces Sooravalli to marry Karuppaiah. Sooravalli accepts . Sooravalli is married to Karuppaiah . In the first night while Sooravalli is sleeping Karuppaiah is shown as a drug addict .
After some days Sooravallis mother is shown talking with a collector asking for the where abouts of Karuppaiah as she could not find her daughter in the house where she was last seen.Mean while the number of dance programmes of Sannasi is rapidly declining as the programme organizers demands a girl like Sooravalli. Sannasi decides to find a new girl for his group. With the help of one of his ex group member (Amudhavanan) he finds a girl dancer who demands lavish facilities for her performace. Sannasi accepts it and his first program after several months with the new girl dancer happens to be a funeral house. After getting money for their performance from the funeral house, Sannasis father Samipulavan scolds Sannasi for performing in a funeral house. Sannasi in turn uses harsh words against his father. Samipulavan gets vexed and goes to a foreign delegates meeting to perform there. The people there praises Samipulavan for his soulful song. Proud Samipulavan returns back to home and challenges Sannasi that he won and he still has the power and divinity in his performance. After this incident Samipulavan dies. Not knowing how to bounce back , Sannasi's group men asks him to talk to Sooravalli for performing in their group getting permission from her husband Karuppaiah. Sannasi finds that Sooravalli did not even turn up for his father's funeral , with whom she use to be affectionate. He asks Sooravalli's mother. Sooravalli's mother says everything about the missing of Sooravalli .
Sannasi goes to find Sooravalli and some how manages to see a building where Karuppaiahs car went. There he sees Sooravalli. He asks her what has happened to her. Sooravalli cries and a flash back is shown . In the flash back the newly wed Sooravalli wakes up from her first night bed and finds an elder man next to her. Shocked by seeing a different man, she hits him badly and severely.Karuppaiah suddenly comes inside and beats her heavily kicking her on her chest. Karuppaiahs men take her to a room. After getting consciousness she peeps through the door to see a few women getting tonsured. She understands that Karuppaiah does brothel and illegal renting of women's womb. Again Sooravalli is shown as a pregnant lady. Another flash back is shown where an astrologer seeks the help of Karuppaiah for a wealthy old man who doesnt have any heir but wants to have a child from his sperm.He believes that a girl child will be born.He also says that he doesnt want the world to know that it is his daughter. But to the outer world the newly born will be an adopted daughter. Karuppaiah bargains for 2 crore rupees and finalizes Sooravalli as the rental mother. When Sooravali finishes the flash back scene, Karuppaih appears and hits Sannasi badly and takes Sooravalli for delivering the baby to a hospital near by. Karuppaiah wants the child to be born at 7.30 am as per the wish of the wealthy old man and his astrologer but the lady doctors tells him that the operation cannot be done as he wishes and warns that any one of the two , the mother or child will die if the operation is done at an earlier stage. Greedy Karuppaiah takes pregnant Sooravalli illegally to a mortuary where the mortuary assistant claims that he will take the child without bothering about the life of the mother. By the time Sannasi reaches the place and a fierce fight follows between Sannasi and Karuppaiahs men. Finally Karuppaiah gets killed by Sannasi. Sannasi manages to get in to the mortuary where Sooravalli's illegal operation is being carried out. When he enters the room, the mortuary assistant attacks Sannasi and gets killed by himself. Sannasi finds Sooravalli dead. At the corner of the room the newly born girl child is shown. The film ends by Sannasi carrying the girl child and walking away
