Kadhir is a petty thief but is an talented strategist, who steals devotional idols from small scale temples. Similarly, Vamsi Krishna is a professional idol smuggler, who steals highly valuable and ancient idols from various temples around the country, and sells it internationally. One day, Vamsi gets know about an emarald Shivalingam Idol, worth crores in a temple at Coimatore. He immediately decides to steal it, and goes to the city and gets friendly with the locals, by introducing himself as a research journalist.
Meanwhile, Vamsi gets to know about Kadhir and his talent for coming up with flawless strategic plans. Hence, he reaches out to him and forms a friendship. After he gains his trust, he manipulates Kadhir into helping him with stealing the emerald Shivalingam idol. With Kadhir's talent and Vamsi's professionalism, they successfully steal the idol.
As the idol is one of the government's prestigious and most expensive property, Kalanjiyam, a vigilance officer starts to investigate about this, and arrests Kadhir as a suspect, who confesses that he stole the idol for the money as he needed it to get settled in life with his beloved, Kushi. He also mentions that the main mastermind behind this entire plan is Vamsi. The rest of the plot revolves around how Kadhir escapes the officer, whether Kalanjiyam captures Vamsi and retrieve the Shivalingam.
All the characters has done a good job. Vamsi Krishna, like in most of his movies is the baddie in this film too, and he has been portrayed stylishly and has also acted well. Kadhir, has performed well with his down-to-earth mannerism, though he is said to be the protagonist of the movie, he is easily over taken by Vamsi and Kalanjiyam, as they are present through out the movie.
Director Krishnasamy, has attempted to make a film which focuses on devotional idol smuggling and how that eradicates the history and culture of the country. While the concept is interesting, the director has failed to utilise the actors talents and to engage the audience as the screenplay was really slow. Shyam Benjamin has scored the music and has done a decent job with it. Thiyagarajan's and Yoga Bhaskar's cinematography and editing skills come to the fore and it is a huge advantage to the film.
In short, Kalavu Thozhirchalai, is slow.
