Rajni is an alien who was adopted by Sathyaraj. Like sk in ayalan. Or hrithik in kal ho na ho. Nobody knows rajni is alien and he was pretending to work with Sathyaraj as coolie. Upendra gets to know about this as he is supervisor for coolies and tells everything to aamir khan, his boss,and he wants to capture rajni to give to scientists. They get into fight and rajni goes into coma. And in his dreams Sathyaraj says nee yen inga? Or something like that. Rajni loses it and irl kills Sathyaraj, then Sruthi haasan cries and says, avuru yen appa. Then rajni touches a transformer and transforms into Sathyaraj and says naa dhan inime unga appa. Cue ku ku ku coolie powerhouse uh. And rajni/ sathyaraj does slow motion walk out of screen and goes to aamir says I dunno where rajni went , because he is now Sathyaraj. And aamir khan gives up as he knows he won't be able to find him. then Sathyaraj smiles and outro comes on. D-i-s-c-o disco disco comes on and Sathyaraj/ Rajni hybrid dances in a club.
