Srikanth's friend, Mani Sundaram (Ramji) is the young son of the temple's chief priest. He is a rationalist, who does not believe in myths and rituals. Instead, he chooses to rationalize his beliefs, and hence often ends up at odds with his father with regard to the temple's mysteries and rituals. One by one, four people are killed inside the temple, including a police inspector who is there to investigate the mystery. At this juncture, Dr. KR (Delhi Ganesh)—once a great psychiatrist, but now intellectually disabled—strays into the village, and is admitted to Oomaisaamy's ashram by Mani. Prasad (Prithviraj), Dr. KR's son, comes in search of him, and ends up being a guest to Mani and his sister Lalitha (Vasuki). As Mani and Prasad try to reveal the temple's mystery even more, they come to know that Dr. KR is actually acting as a retard, and he too is trying to do the same. But Dr. KR has personal intentions. He had been regarded as one of the best psychiatrists of India, and an Indian Central Minister admits his intellectually disabled son to his hospital for treatment. But Dr. KR is unable to cure the Minister's son even after giving his best for the patient. Enraged by this, the Minister ridicules Dr. KR and moves his son away to Oomaisaamy's ashram after hearing other people speak so highly about it. Dr. KR feels insulted and decides to find out how Oomaisaamy is able to cure patients so effortlessly in his ashram. To achieve this, he makes everyone believe he is retarded, and lands up in Oomaisaamy's ashram. What Dr. KR does not know, is that he was unable to cure the Minister's son not because of his incompetency, but because of a sinister scheme laid out by his junior, Dr. Vishwaram (Mohan V. Ram).
