Its the concept of kARMA(WHAT WE DO IS WHAT WE FACE)
The movie is terrific?? and I really loved it??.If you are curious enough then watch it.you will definitely enjoy it.
Actually the movie is a remake of kannada movie uturn.But with some changes it was done in telugu i.e., all about mystery of r.k.puram flyover and mainly character done by Samantha ?????? lovely and all characters very well done.
