'Chori Chori' is a romantic story telling the story of Ranbir (Ajay Devgan) and Khushi (Rani Mukherjee) who are as different as chalk and cheese. They bump into each other on the streets of Delhi. It certainly isn't love at first sight for them. In fact there is nothing but war of words and arguments. Circumstances keep Ranbir and Khushi together, much to their discomfort. Till they realize that they cannot do without each other.
