Mareechan (Jayaram) disguised as a deer to attract Sita for Ravana gets killed by Lord Rama's arrow. He is also cursed that he will remain a rock, till somebody comes to free him after a few centuries.
Then the story jumps to the modern day. Rajaram (Nasser) is a rich estate owner in Ooty whose relatives, M.S. Bhaskar, Ilavarasu and Mayilsamy exploit him and wait to loot the entire property.
