For astrological reasons, a father (Azhagan Thamizhmani) has to leave his son Rudran (Arya) in Kashi for 14 years.

14 years later, repenting his act, he goes with his daughter in search of the boy. He finds him there but is shocked to learn he has become an Aghori, a fierce, tigerish sadhu who gives moksha and prevents the soul from getting reborn. Nevertheless, he brings him back to Tamil Nadu as he had promised the boy's mother (Vijaya Bharathi).

The story takes a turn here and introduces us to the world of physically and mentally challenged beggars, a world controlled by the cruel Thandavan (Rajendran). Hamsavalli (Pooja Umashankar) is a blind girl who was with a group of street actors, but on one day was forcefully separated from her troupe and made to join the beggars controlled by Thandavan. Soon, she becomes a victim of Thandavan's cruelty.

Meanwhile, Rudran leaves his house to find his place in a small cave near a hill temple. One day, Rudran's mother comes to plead with him to come back to their house but is unsuccessful. Following this, Hamsavalli tries to convince Rudran to return to his house, but fails. In the meantime, Thandavan makes a deal with another man of the same profession to sell some of his beggars to him for a tidy profit. The man forcefully takes the beggars away, although they want to stay with the rest of the beggars. He then returns with a man with a deformed face trying to force Hamsavalli to marry him for 10 lakhs worth of money. Thandavan orders his men to bring Hamsavalli, but they take her to Rudran to help her. Rudran kills the new man and is arrested by the local police, who are forced to let him go as they are not able to locate the body and are afraid of forcing a confession from Rudran for fear of being curse. This agitates Thandavan.

Hamsavalli seeks protection and solace from the church, but Thandavan finds her and tortures her as she refused to marry the deformed man, thus making him lose out on a good amount of money. An angered and humiliated Thandavan beats up Hamsavalli badly. Rudran is shown wounded in his forehead, with blood oozing out. In a flashback, Thandavan appears face-to-face against Rudran and fights him, the result of the fight being the wound. Rudran kills Thandavan. Hamsavalli finds her way to Rudran and beseeches him to free her from her misery and the earthly life. She also pleads with him to grant her moksha so that she never has to be born again. Rudran slashes Hamsavalli's throat, performs her last rites and returns to his guru in Kashi.
