Is fate really destined? On an ordinary, hectic Christmas Eve, Jonathan (John Cusack) and Sara (Kate Beckinsale) meet eee. Within a few hours of knowing each other, they fell hopelessly in love with each other. Although, they each have their own circle of life, their own partners. When they happily wandered the streets of Manhattan all night, dawn came, and they had to face reality. Sara rejects Jonathan's request to keep each other's numbers and decides that it's up to God. A few years passed by and they never met again. At this time, Jonathan is ready to step into the marriage hall, and Sara has also received her boyfriend's engagement ring. It's just that a book and a movie poster can involuntarily remind them of that Christmas Eve a few years ago. Jonathan began his quest for Sarah on the eve of his wedding, relying on clues left behind years earlier.
