Prashant Kumar Sharma (Anil Kapoor), a part-time vocalist in an orchestra, who is popularly known as Fanney Khan, dreams of becoming a singer but circumstances prevent him from being one. He rushes to the hospital and holds his newborn daughter, whom he names Lata, which is the name of the famous singer, Lata Mangeshkar. A grownup Lata ("Pihu Sand") has an excellent voice but is ridiculed because she is overweight. She is a fan of Baby Singh (Aishwarya Rai Bachchan), a famous singer, who is tired of her life and wants a break. Prashant's factory is closed and he starts working as a taxi driver. One day, coincidentally, Baby travels in Prashant's taxi. When she asks for water, Prashant mixes sleeping pills in the water bottle. He calls his best friend Adhir Sinha (Rajkummar Rao) and tells him that he is kidnapping Baby to release an album of his daughter. After much pleading, Adhir agrees to help him. During this incident, Adhir and Baby become friends. Adhir finally takes her out and she starts enjoying herself. She also thanks to him for bringing her dog, Ustaad, who she considers to be her true friend but problems arise when Prashant sees on TV that the police are aware of Baby's kidnapping as the watchman of Baby's residence reveals that he saw a man (Adhir) kidnap her dog. While wearing a mask of Rajnikanth, Prashant asks Baby's director Karan Kakkad (Girish Kulkarni) to release an album of his daughter. Lata is excited about her own album, and after recording, she talks about her experience, leading the director to realize that her father is the kidnapper and is the famous Fanney Khan. He recognizes him in their next meeting. Prashant finally removes his mask and reveals that he can trust him and his friend Adhir. Lata replaces Baby as the performer on the reality show India ki Awaaz. Meanwhile, Adhir and Baby are nowhere to be found. Police and TV arrive outside Prashant's factory and surround the premise. Prashant calls Kakkad and asks him what is happening and Kakkad tells him to walk outside and tell the Police and TV that if Lata does not perform, he will shoot the real Baby. The TV reporters patch Prashant through with the TV placed inside India ki Awaaz and Prashant and Lata have an emotional talk. She performs well and stuns the audience. Later, Prashant walks out of the factory with his hands up but to his surprise, the Police and TV men clap for Prashant. Later, a video is released depicting Baby and Adhir in a live-in relationship and on vacation. They both state that they are fans of Lata Sharma. The film ends with the society praising Lata and the hard work done by Prashant to make his daughter a singer.
