In an Indian village, a struggling barber sees his luck begin to turn when residents learn that a famous actor he once knew is coming to town.
Based in Budbuda, Uttar Pradesh, Billu Vilas Pardesi barely makes a living as a barber. 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.
Billu is a movie about a barber residing in a village who is friends with a well known actor. The thing is Billu is poor and thinks his childhood friend has forgotten him and thus stays away from making any move. When the news of shooting a film at the location where Billu stays comes up, the family of Billu lightens up – but will that stay?
