Sugam Mishra, a newly recruited RPF constable, is posted in Patna, where he struggles to prove himself while dealing with his overbearing father and his new marriage. Afroz Hamza, a talented but socially awkward computer geek, develops software that can successfully book Tatkal tickets, hoping to use his skills to win over the girl he loves. Hamza's uncle Mama recognises the commercial potential of his software and turns it into a business, creating a network of agents to sell confirmed Tatkal tickets at a premium. As the business grows, Hamza and Mama become increasingly involved in the illegal ticketing network, while Sugam begins to notice irregularities and suspects a large-scale scam. Sugam takes matters into his own hands and investigates the network, eventually identifying and arresting hundreds of ticket agents involved in the racket. Hamza and Mama face increasing competition, betrayal and personal setbacks as their operation expands, while Hamza's pursuit of success is complicated by his need for love and recognition. Sugam's investigation eventually leads him to the masterminds behind the racket. As Hamza plans to escape to Dubai, Sugam tracks him down and brings the Tatkal scam to an end.
