"Jaane Tu... Ya Jaane Na" is a nice romance...a good film for a date movie. When it begins, Jai (Imran Khan) and Aditi (Genelia D'Souza) are very good friends and have been for many years. They love to spend time with each other and although they are the opposite sex, they never have had any romantic notions towards each other. Instead, they are best friends....though folks around them assume the two will eventually marry. But when her parents propose that, the two are flabbergasted and quickly dismiss this notion. As a result, the two agree to help each other find the ideal spouse. Sadly, the girl chosen for Jai has a hellish family and the guy for Aditi turns out to be a violent jerk. Can Jai and Aditi recognize that their new partners are just not right for them and they get together themselves?
A soft-spoken man and a hot-tempered woman are pushed to get married by their family and friends. Convinced that they are not suited, the best friends decide to seek out a soul mate for the other.
