This is a romantic comedy about
two New Yorkers, Jonathan Trager ( John Cusack) and Sara Thomas (Kate Beckinsale)
who meet each other in a Manhattan department and discovers an unexplainable
chemistry between them. But unfortunately both are seeing other people.
When Jonathan suggests that they exchange phone numbers, Sara, a believer
in fate and coincidence, writes her name and number in a book which she
says that she will sell to a used bookstore and if Jonathan ever finds it,
they are destined to be together.
