  During the Christmas season in New York City, Jonathan Trager (John Cusack) meets Sara Thomas (Kate Beckinsale) trying to buy the same pair of black cashmere gloves at Bloomingdale's. They feel a mutual attraction and despite the fact that each is involved in other relationships, they end up eating ice cream at Serendipity 3 together. Soon after they exchange goodbyes. However, Sara and Jonathan both forgot something at the ice cream bar. They return to get their things only to bump into each other again.
  Considering this to be a stroke of fate, Jonathan and Sara decide to go out on the town together. They ice skate on the Wollman Rink at Central Park. At the end of the night they exchange phone numbers. Sara writes hers down, but it flies away with the wind. Johnathan asks her to write it down again, but she takes the number flying with the wind as a bad sign. Wanting fate to work things out, Sara asks Jonathan to write his name and phone number on a $5 bill which she immediately spends. He tells her it is unfair that she has a chance of finding his information, but he has no chance of finding hers. Therefore, she shows him the book in her purse Love in the Time of Cholera and she says she will write her name and phone number on the inside cover and sell it to a used book store the next morning. If they are meant to be together, they will find the items and contact each other.
  Jonathan is not satisfied with this so they go into the Waldorf-Astoria and enter into different elevators and she tells them that if they both choose the same floor, they are meant to be together. She tells him her name is Sara as the doors close. They both choose floor 23. Jonathan's elevator stops on 14 and a little boy presses all the buttons causing Jonathan to arrive on floor 23 seconds after Sara leaves, after having arrived there and waited for several minutes. The two believe they've lost each other forever.
  Several years later, Jonathan is at an engagement party with his fiancÃ©e Halley Buchanan. On the same day Sara comes home to find her boyfriend Lars Hammond (John Corbett), a famous musician, proposing to her. As their wedding dates approach, each find themselves with a case of cold feet resulting in each attempting to find each other again.
  Jonathan returns to Bloomingdale's after finding an old receipt inside one of the cashmere gloves in an attempt to find Sara. He meets a salesman (Eugene Levy) and eventually, with the help of his best friend Dean Kansky (Jeremy Piven) and the salesman, Jonathan gets an address. After additional research, Jonathan and Dean meet an artist who recalls that Sara lived with him for a short time after being referred by a placement company. The artist describes the company's location to them as a shop next to Serendipity 3. Jonathan and Dean follow the lead to find that the agency has moved and its former location is now a bridal shop. Jonathan takes this as a sign that he is supposed to stop looking for Sara, and decides that he should marry Halley.
  Sara decides to surprise her best friend Eve with a trip to New York and stays at the Waldorf-Astoria, hoping that fate will bring her to Jonathan. During there stay they happen to visit the same locations that Jonathan had gone to the previous day. Later on, Sara and Eve visit Serendipity to celebrate Eve's birthday. Eve is handed a $5 bill as change. Back at the Waldorf-Astoria, Eve bumps into an old friend from college â Halley â who is there for a wedding rehearsal. Halley invites Eve and Sara to the wedding without anyone realizing the groom is Jonathan. Sara returns to her hotel room, where she finds Lars, who followed her to New York. While with Lars, she sees Cassiopeia in the sky and realize she doesn't want to be with him. Thus, Sara breaks off her engagement with Lars.
  The night of the rehearsal, Halley hands Jonathan a copy of Love in the Time of Cholera as a gift, having noticed him picking up the book every time they're in a bookstore. It is the copy that Sara had written in, and he immediately sets off to find her. He and Dean fly to San Francisco and when they arrives at her house, they observe Sara's sister, Caroline, inside being intimate with her husband. Thinking it is Sara and now feeling foolish and defeated returns home for his own wedding. Dean tell Jonathan " Didn't you said everything happen for a reason? maybe we standing here because you don't want to be standing somewhere else."
  Sara decided to go back home, she finds that her wallet has been mistakenly switched with Eveâs. As she reaches inside to pay for a head set (for the in-flight movie) she realizes the $5 bill she hands to the flight attendant is the one which Jonathan wrote on several years earlier. She takes the $5 bill and gets off the plane to search for him. His neighbors tell her heâs getting married the same day. She rushes to the hotel, only to see a man, apparently cleaning up remnants of the end of the ceremony. Sara asks the man if the wedding is over, and he says yes. As she is in tears and turning to leave, thinking that Jonathan already got married and she was too late, the man says Sara will get her wedding gift back because the wedding was called off.
  Eve gets in a cab to go to the airport and tells Sara to put on a jacket because is freezing. Sara remembers she left her jacket in Central Park.
  Jonathan, while aimlessly wandering around, finds himself in Central Park. He Comes upon Sara's jacket while sitting on a park bench and eventually wanders out onto what was a skating rink the first day they met (but now is a roller-skating rink during the warmer weather) and spent together. He lies down on the rink surface and uses the jacket he finds as a pillow. As snowflakes begin to fall, a black cashmere glove falls on his chest. He turns on his side to see his black cashmere glove.
  Realizing he has them both, he looks up to see Sara. They introduce themselves to each other formally for the first time. The film concludes with Sara and Jonathan at Bloomingdale's, enjoying champagne on their anniversary at the same spot where they first met.
