Thuppakki is basically about Jagdish (Vijay), an army captain, who returns to Mumbai for a 40 days’ vacation. He has a loving family, comprising two sisters and his parents, who wish to get him married to an appropriate girl. After some cat and mouse episodes with Nisha (Kajal), the arranged bride, Jagdish’s personal life is set with her. 　　On the other hand, he has a greater task at hand as he has to eradicate sleeper cells that are out to bomb and terrorize Mumbai across 12 prominent localities. These sleeper cells are controlled by one main man (Vidyut Jamwal) who is also later drawn into the city thanks to Jagdish’s proactive and intelligent moves in eliminating the cells through a secretive mission which he carries out with the help of his colleagues, who assemble for a marriage. 　　Later it becomes a straight game of one-upmanship between the main man and Jagdish. How Jagdish vanquishes him and how Jagdish manages to save the lives of people who are lured into this mean battle, is the remaining part of this extravagant and stylish entertainer which rides on the ever-dependable Vijay. 　　Vijay plays the role of an encounter specialist while Kajal Agarwal plays the character, Nisha, an iron-willed girl.
