Plot (concise) Billu (Irrfan Khan) is a humble barber in a remote village whose life is upended when a big film production arrives nearby. The villagers thrust Billu into the spotlight by claiming he’s childhood friends with superstar Sahir Khan (played by Shah Rukh Khan in a cameo-heavy role). Billu faces mockery, opportunism, and his own pride as he navigates expectations and decides whether to reveal the truth about his relationship with Sahir.
