Mahender Singh Hooda aka Montu is a lazy, uninspired, and unprofessional physical training instructor (PTI) at a school in Haryana, a job he got courtesy of his father Kamlesh Singh Hooda’s influence as a lawyer. He lives with his parents and his brother and spends most of his time hanging out and messing around with his teacher-buddy, Mr. Shukla. When Neelima Mehra arrives in Montu’s school as a new computer teacher, Montu finds himself falling in love with her, and the two start to grow very close when she tells her nickname Neelu.
To his surprise, Montu finds out that the school hired a new PTI, Inder Mohan Singh, as the government required PTIs to have a physical education degree, which Montu didn’t have. Begrudgingly, Montu accepts a role as Inder Mohan’s assistant. Montu quickly realizes that Inder Mohan is a much better PT teacher than him, and gets even more irked when Neelu starts spending more time with Inder Mohan. One day, Inder Mohan keeps Montu’s brother, Babloo, pinned to the ground as a punishment for not paying attention. This leads to a fight between Montu and Inder Mohan, after which Montu quits his job at the school.
