Mukkabaaz is the story of an aspiring lower caste boxer Shravan (Vineet Kumar Singh) who trains under Bhagwan Das (Jimmy Shergill) who is the general secretary of the state boxing association as well as the local kingpin. Shravan trains hard but is relegated to a helper in Bhagwan’s house. Shravan falls in love with his niece and elopes with her to get married. On hearing about the incident, Bhagwan makes Shravan’s life miserable and expels him from the federation. Despite all opposition and humiliation, Shravan stops at nothing to achieve his victory at the Indian National Boxing Championship.
