Embedded with action and suspense, this socially relevant drama sparks off when Ravi (Suresh Gopi) is attacked by a group of people on a rainy night. His friend Gopan (Jayaram) finds Ravi unconscious on the road and seeks help from the Police. By the time Gopan arrives with the police force, Ravi is missing.
The story then flashes back to a few months back when Ravi followed by Gopan arrives at Shanthigiri monastery for research. Vishnuji, the spiritual head is running the monastery with the help of aid from foreigners. While Ravi idiolizes Vishnuji, Gopan only sees in him a fraud.
Both the young men become friendly with Vishnuji's (Charuhasan) private secretary, Maya (Sithara). Very soon, Ravi and Maya find themselves attracted to each other, while Gopan helps them express themselves and start their relationship together.
Aryadevi (Sreevidya), another spiritual leader visits Shanthigiri and it is revealed that she is Ravi's surrogate mother. Also it is revealed that Arya Devi was in an intimate relationship with Vishnuji and she accuses Vishnuji of pimping her to foreigners to collect money to start Shanthigiri monastery. Arya Devi requests Ravi to come back to their monastery, but Ravi rejects the idea.
Back to present, a shrewd Police Officer (Thilakan) is assigned to investigate Ravi's's disappearance. After lot of revelations from many characters, he finds that Ravi had come to know about malpractices going on in the monastery including prostitution and had threatened Vishnuji to bring him down.
Also Maya confesses to having overhearing Vishnuji's conversation with her father about the murder of Ravi. Vishnuji gets arrested, but his lawyer (Nedumudi Venu) establishes in court that Ravi is alive and is in hiding, while Gopan is a mental patient and can't be trusted. Finally the Court ends up acquitting Vishnuji of all charges and he goes out to a roaring welcome from his supporters.
Disgusted with the failure of the judicial system, Gopan decides to take the matter into his own hands and doles out his own version of Justice. Will he succeed in beating Vishnuji at his own game?
