A reputed cop from Tamil Nadu takes charge in Andhra Pradesh to solve the mysterious murder of a top police officer, and takes on local thugs and criminals during the course of his mission.

Dr. Vasi (Rajnikanth) invents a super-powered robot, Chitti, in his own image. The scientific body, AIRD, that must approve the robot, declines it based on its not having emotions and the ability to make rational judgment. A sudden flash of lightning evokes emotions in the robot, and Chitti is seemingly ready for integration into the human world. Then, Chitti falls in love with Dr. Vasi's fiancée Sana (Aishwarya Rai) and turns on his creator. Written by Joyojeet Pal
