Sandra Bullock plays Lucy Ellenore Moderatz, a lonely fare collector on the Chicago elevated railway. The highlight of her days is selling a token to a handsome commuter, Peter Callaghan (played by Peter Gallagher), on whom she has a secret crush. Working on Christmas, Lucy witnesses Peter being mugged and pushed onto the tracks, and she rescues him from an oncoming train. Peter falls into a coma and she accompanies him to the hospital, where she fantasizes aloud, "I was going to marry him". A nurse overhears her and, misinterpreting the situation, tells the head physician, a policeman and Callaghan's family that Lucy is his fiancée. At first Lucy is too caught up in the madness of everyone's panic to tell the truth, and after that she is too embarrassed to.An orphan with few friends, she becomes so captivated with the quirky Callaghans and their unconditional love for her, that she cannot bring herself to hurt them by revealing that Peter doesn't even know her. She spends a delayed Christmas with the family so "they can get to know each other". Lucy then meets Peter's younger brother Jack (Bill Pullman), who has taken over his father's business and is always working. Jack is very suspicious at first, saying Peter never mentioned Lucy or a marriage, which is not like him. Later on, after spending some time together to get acquainted, Jack starts to realize that he himself has feelings for Lucy.Then complications arise. Peter wakes up, not remembering Lucy at all, but by this time the rest of the Callaghan family has become so enamored with Lucy that they all naturally assume that Peter must have amnesia. Forced by his family, Peter and Lucy spend time together, while Lucy doesn't know how to tell them the truth, especially now that she has fallen in love with Jack. Peter is convinced by Saul (Peter and Jack's godfather, who knows about Lucy's secret) that Lucy must be his true love if he really proposed to her, so he does it "again". Lucy freaks out by the unexpected questions and agrees. Lucy confides in the kindly Saul, who believes that Lucy belongs in the family. Yet the elderly widower can't bring himself to tell the family about Lucy either. Lucy forces herself to be happy; she's with the man she wanted to be with her whole life.The day before the wedding, Jack visits her to give her a present - a snowglobe of Florence, Italy, the place that she has always wanted to go to. As he leaves, Lucy asks him if he could give her any reason why she shouldn't marry Peter. Jack hesitates before saying that he cannot give a reason, and angrily leaves.On the day of the wedding, Lucy starts to feel more and more guilty over her lie and her feelings for Jack, when it's actually Peter she's marrying. She walks down the aisle, where Peter is waiting with Jack, who is his best man. The priest begins, but during the words "Dearly beloveds, we're gather here today...", Lucy suddenly objects. Jack is surprised and objects too. She tells the family who she is and what went wrong in the hospital. She tells the parents she's fallen in love with their son, but points out that it's not Peter, but Jack.
