The film starts off with the introduction of Adi Tomar aka Adi (R. Madhavan), who, by profession, happens to be a coach of the girls' boxing team. Courtesy the dirty politics (wherein he is falsely accused of sexual harassment), he gets transferred to Chennai. Adi is now on a lookout for a girl who has the much required passion for the sport and fire in her belly. And his search ends in the most unlikely person for the job Madhi (Ritika Singh), who, despite being a fisherwoman by profession, is a born talent in boxing and she idolises Mohammad Ali. After having agreed to pay Rs. 500 per day towards her training, Adi takes her under his wing. On the other hand, Madhi's elder sister Lakshmi aka Laks (Mumtaz Sorcar) also happens to be a boxer wanting to get into police department so that she can take care of the family. Seeing Adi's closeness and confidence in Madhi, Laks plays a dirty game with her own sister, this resulting in Madhi's ouster from an important match. Unaware of the real reason for Madhi's dismal performance, Adi gets wild on her at her poor performance and throws her away from his life and training. Situations then take a U-turn which leads to the imprisonment of Madhi who also escapes from being a prey of chief selector's desires. What action of Madhi leads her to be jailed, who is the person who tries to take advantage of her, does Adi ever get to coach his once favourite student Madhi all over again, what ultimately happens to Adi and Madhi is what forms the rest of the story.
