Ambujakshi alias "Ambu" (Trisha Krishnan), a film actress, arrives in Europe to spend the vacations with her friend Deepa (Sangeetha Krish), a divorcee and her two children. While going in a taxi, Ambu recalls an early incident regarding her ex-boyfriend Madhanagopal alias Madhan (R. Madhavan), a wealthy entrepreneur: Three years ago, she was shooting for a film with actor Suriya in a bright park and Madhan was suspicious of her relationship with the actor. While returning, he lets Ambu drive his new car. Madhan advised Ambu to stop acting, but Ambu claimed it as her profession which she cannot give up, leading to an argument that caused their car to crash near a rock. At the same time they blamed a small white car that just passed by, to be the reason for the crash. Unable to bear any more arguments, Ambu broke her relationship with Madhan and walked away.
