Khushi (Rani Mukerji) is a happy-go-lucky orphan living in Delhi. She meets Ranbir Malhotra (Ajay Devgn) through a chance encounter one day before she is fired from her job. He tells her about a dream house that he has built in Shimla. After being dismissed from her job, she locates the bungalow and moves in, informing everyone that she is Ranbir's fiancée. There she meets Ranbir's family and Pooja (Sonali Bendre), Ranbir's love. When Ranbir returns, at first he is outraged at Khushi's intrusion in his life but then decides to play along with her to make Pooja jealous and fall in love with him. Khushi and Ranbir end up falling in love. However, Khushi's close encounter with reality and Ranbir's old commitments hold them back for a long time before they finally listen to their hearts.
Sukanya Verma of Rediff.com wrote, "Chori Chori is a Rani Mukerji film all the way. All the other actors have done their parts perfectly. The climax would have been better if wasn't so melodramatic and didn't have to carry the weight of two songs. What makes Chori Chori likeable despite its shortcomings is that it has a 'heart' -- the prime ingredient for any love story."[9]
Taran Adarsh of Bollywood Hungama wrote, "Although Chori Chori has an interesting storyline, it suffers on account of a hackneyed screenplay. A story like this may've worked a few years ago, but it holds minimal appeal in the current scenario. The film starts off pretty well, but runs out of steam in the second half, mainly because too many songs have been incorporated forcefully."[10]
