Serendipity is a surprisingly tender and gripping romantic comedy. The plot follows two people in two separate, seemingly happy relationships. They find each other serendipitously when shopping at Bloomingdale's and enjoy a wonderful night together over coffee and ice skating in downtown New York City. Sara (Beckinsale) believes that if they are meant to be together then fate will bring them back together. So she asks John (Cusack) to write his name and phone number on a $5 bill; then uses it to pay for a pack of gum. She writes her name and number on the inside cover of her favorite book, Love in the Time of Cholera, and sells it to a used bookstore. Will they find each others' names and numbers or were they never destined to be together?
