Maruthu

Maruthu is a labourer from Thalaivankottai working in the Rajapalayam vegetable market who does not tolerate injustice. He leads a happy life with his grandmother, Appathaa, and his close friend, Kokkarako. While working at the market, Maruthu sees some goons chasing his girlfriend Bhagyam and her father. He beats up the goons and learns from Bhagyam's father that her mother, Mariyamma, was a brave woman who stood up to the atrocities committed by the municipal chairman, Rolex Pandiyan, against the local people. When Mariyamma decided to run against Pandiyan in the upcoming municipal election, Pandiyan and his men brutally hacked her to death. Bhagyam and her father are unable to prove in court that Pandiyan committed the murder. Appathaa, who witnessed Mariyamma's brutal murder, gets upset that she did not stop it and has Maruthu married to Bhagyam to repent her earlier actions. Maruthu also promises to avenge Mariyamma's death. A cat-and-mouse game ensues with Pandiyan using all means to stop Bhagyam and Appathaa from testifying against him, but to no avail. At the court, Appathaa testifies against Pandiyan, who is issued an arrest warrant. In retaliation, Pandiyan kidnaps Appathaa and brutally tortures her to death. Enraged, Maruthu single-handedly fights Pandiyan and his gang, kills them all, and performs Appathaa's funeral rites.
