Mookaiyah and his sister Bairavi are the children of a drunkard. They are separated after Bhairavi gets lost in an accident. Following this, Mookaiyah becomes a servant of a local landlord. Mookaiyah is a loyal servant and does whatever is asked of him. The landlord, Rajalingam, forces Mookaiyah to abduct a young girl from a neighboring village, Bhagyam. Rajalingam rapes her in the absence of Mookaiyah. Maanikam, Bhagyam's adopted brother, finds to know about the incident. When the police investigate Maanikam, Mookaiyah discovers that Bhagyam is his long-lost sister. Then he immediately approaches Rajalingam and forces him to marry Bairavi; he was not ready to accept it at first but after a while he promises to Mookaiyah that he will marry Bairavi. As Mookaiyah was the person who abducted Bairavi, the police suspect that he is the culprit, comes to Rajalingam's house to know about Mookaiyah. Rajalingam also alleges to Police that Mookaiyah only raped Bairavi. The police therefore arrest Mookaiyah, based on the statement of Rajalingam. Meanwhile, Rajalingam plans to kill Bairavi when she was in an unconscious state in hospital. If Bairavi become conscious and gives a statement to the police then he will definitely be prone to punishment, so he kills her. After knowing about his adopted sister's murder, Maanikam vows to take revenge on Mookaiyah, whom he believes to be responsible for Bairavi's death. Meanwhile, Mookaiyah escapes from jail knowing about the incident. He then sets out to kill the landlord in revenge for his sister's death.
