Dr. Vaseegaran creates Chitti, a powerful robot in his own image, but it is rejected by the scientific body AIRD due to its lack of human behaviour and emotions. After a lightning strike triggers emotions in Chitti, he begins to develop human-like feelings. However, Chitti falls in love with Dr. Vaseegaran's fiancée, Sana, and turns against his creator, leading to dangerous consequences.
