Adhering to the sentiment of any Rajini film, Endhiran also will have the intro song of super star sung by the veteran singer S.P Balasubramaniam.
The song goes like this:
“நான் கண்டது ஆறறிவு; நீ கொண்டது பேரறிவு
நான் கற்றது ஆறுமோழி; நீ கற்றது நூறு மொழி”
Naan kandadhu aararivu, nee kondadhu perarivu
(I have witnessed six senses, (but) you are bestowed with erudition)
Naan katradhu aaru mozhi, nee katradhu nooru mozhi
(I have learnt six languages (but) you have learnt hundred languages)
Endhiran is about an intelligent scientist Dr Vaseegaran who is well versed in the latest technological innovations of science. He creates a robot which looks just like a human and has all the features of a normal man.
He introduces this robot to the world. At one point, the human-look alike robot goes out of control and the cascading events form the main storyline of Endhiran.
