After a year, A blind man named Kenny Thomas lays flowers on the memorial and mourns someone's death during the bomb blast.

Sara Vinayagam, a British-born Anglo-Indian woman, wins the Miss London title, and to build her social profile, she goes to Kenny's church and acts like she is helping out there.

As the autopsy of the murdered victims takes place under Sara's father, Veerakathi visits him and learns about Kenny, who is admitted there for a small accident.

Sathyan is released and meets Sara, and both of them go to a place (which she learns of from Kenny's phone, which he misses during a fight with the local thugs).

Shiva soon realizes that Sharath is the mastermind behind the missing flowchart, as he sold it to a terrorist group, with some help from the London militants.

After burning Sharath with the Metal Melting Machine in Victor's (Sharath's friend) factory, the India Union Minister requested Kenny to come back to India as Shivakumar, but he rejects the request as Kenny's former identity as Shivakumar had died and he is going to spend his life for Meenakshi.

UTV Motion Pictures commenced an innovative title contest in Twitter, and it received massive response from Vikram fans.

[5] Vikram was revealed to play the role of a blind man, who practices the technique of human echolocation, the ability to detect objects, their position and size by sensing echoes.

[4] While "delays in getting the visa for the entire cast and crew" was the official reason given for the change of location from the US to the UK, sources told that the move was also necessitated to keep the budget from skyrocketing.

[21] The film helped raise ₹2 million (US$23,000) for the National Association of Blind (NAB) through its premiere show donor passes.

The Times of India rated the film 3/5, writing "Director Vijay and actor Vikram collaborate again in this movie after their earlier successful outing in Deiva Thirumagal, And Thaandavam'has everything going for it – big cast, good locations, a story with potential and a competent director – yet the result is far from satisfactory because of a weak and meandering screenplay, and poor pacing.

[28] Sify's reviewer claimed that it was "Vikram and him alone who diverts your attention from the film's little logical script flaws and spellbinds you with an endearing act that is Thaandavam's biggest strength".

Tamilko wrote: "Thaandavam’s dreary screenplay hampers the much needed pace for a film set in espionage backdrop.
