Thandavam is a 2002 Indian Malayalam-language action film directed by Shaji Kailas, written by S. Suresh Babu, and produced by Johny Sagariga.
The reciprocal justice is carried out by Kasinathan who in a strategic move corners Shankar Das in a compromising position with a serial actress and blackmails him to release permission for water supply in the village.
Ensuing celebration is amply enjoyed in a rain dance song by Kasinathan with all and sundry of his devoted satellites, including characters Murugan, Vellapulli Mathachan, Tomi, Basheer, Pushpakumaran, etc.
The upcoming businessman Dasappan Gounder and his henchmen smell an opportunity to market Cola drinks in Midhilapuri and approach Swaminathan to start a mutually profitable business deal.
In a chance encounter, Kasinathan learns of his elder brother's death as a planned murder by Gounder, DYSP, and Shankar Das.
He is eventually caught in the middle of the Kayakalpa treatment at an ashram and goes mad in the end, just retribution for a life full of sins and debauched deeds.
