Introduction:

Tom and Hannah met at Cornell University in 1998 when he accidentally slipped in her bed thinking she was his lover, Monica. He was impressed by her honest personality and how she did not fling herself at him.

Ten years later, Tom (Patrick Dempsey) is very successful. He has become wealthy from his invention of the “coffee collar,” has plenty of guy friends, and a new girl every week. Hannah has remained his friend. It is obvious that she is crazy about him, even as he takes her for granted.

Hannah (Michelle Monaghan) goes to Scotland on an acquisition trip for her museum and Tom realizes he feels empty without her. He becomes dissatisfied with his relationships with other women and decides to tell Hannah his feelings when she returns. However, when Hannah comes back, Tom learns that she has become engaged to wealthy Colin (Kevin McKidd) and that the two plan to move back to Scotland. Hannah asks Tom to be her “maid” of honor and he agrees so he can try to stop the wedding and win Hannah back.

While in Scotland, Tom plans to tell Hannah he loves her. They share a passionate kiss at her bachelorette party, then break away. Hannah then gets whisked off by her bridesmaids. That night, Hannah goes up to Tom’s room to talk to him. But before she arrives, Hannah’s cousin, who Tom broke up with, comes into Tom’s room and attempts to seduce him. Hannah walks in right as Hannah’s cousin is on top of Tom. Tom and Hannah have an argument, and Tom leaves for home. On his way back, he decides to stop the wedding. On horseback he makes it to the chapel just in time, and kisses Hannah, who decides to cancel the marriage and marry Tom.
