His wife, Bindiya, looks after the household, and his children, Gunja and Ronak, are on the verge of being expelled from Gyaan Bharti Vidyalay Higher Secondary School due to non-payment of fees. Then everything changes when Bollywood actor Sahir Khan makes an appearance to film a movie in the town. Rumors spread that Billu is Sahir's close friends, and he becomes a celebrity virtually overnight. His shop gets donations and clientèle, and the school decides to educate his children for free. The trouble begins when townsfolk want to meet with Sahir but Billu is unable to contact him.
