An human-android contructed by a scientist falls in love with the to-be bride of his creator.
      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 emotion and the ability to make rational judgment. A sudden flash of lightning evokes emotion 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 turn on his creator.
