After helping out social worker Kajal (Ileana D?Cruz) whilst dressed as a Police Inspector for a photo shoot, she mistakes him to be an Inspector, and he plays along. After traveling to Mumbai to pursue his acting career, he is mistakenly published in the newspaper as an Inspector, which his mother sees. She arrives in Mumbai to see her dream come true, and circumstances lead Vishwas to carry on his lie not only to Kajal, but also to his mother.
