A man named Kulasekaran comes to Vanarajapuram forest with his wife and little son Karzan to find the secret of Amirdharasam (elixir of life) after fighting with his father Veerasingam, who disapproved of his plan to be in the forest. After considerable efforts for several days, Kulasekaran finds the Amirdharasam secret, which he writes in a piece of paper and locks it inside a locket on Karzan's necklace. Veerasingam, on learning of the death of his son, comes to the same forest with his adopted daughter Leela to find his grandson.
