text: Plot Ramanaa begins with the abduction of 15 Tahsildars across various parts of Tamil Nadu. After three days in captivity, 14 officers are released, but one's body is found in Trichy. The police find a tape recording and a file on the dead officer's body that provide significant evidence concerning the kidnapping and subsequent murder. The files suggest that the crimes were committed by members of the self-proclaimed "Anti-Corruption Force" (ACF), a citizen militia seeking to eliminate corruption through vigilante acts. The group proclaims that they will kidnap top 15 corrupt officials in each department, keep them in captivity for a week and kill the most corrupt one.
  The film's setting then shifts to Dr M. Ramanaa, a mild-mannered professor at National College in Chennai, who lives in a house with four adopted kids. While treating his adopted child at a big private hospital, Ramanaa discovers that the officials at the facility are engaging in extortion and fraud. After sending his kids home, he goes to the Govt hospital, brings a recently dead poor man's body to the private hospital and tricks them into treating a dead man. The hospital staff fall for the trick and try to extort a heavy sum using the body. Ramanaa pays all the fees and collects all the documents. When the doctors inform him that the patient is dead, he reveals the trick. Rishi, who is the hospital's heir bargains with him, but eventually pays Ramanaa two millions rupees. Ramanaa takes the money he paid the hospital and gives the remaining huge sum to the poor man's family. He also sends copies of the reports to the incoming President of India Dr A.P.J Abdul kalam. Due to government pressure the hospital and college are closed off.
