Holly's great aunt, Lillian, is known for matching people with great success. So she has, among other things, done with Holly's brother and her best friend who is now getting married. At a party for the newlyweds, Lillian pairs Holly with Chris, Holly's brother's college friend and future best man. But Holly and Chris really don't like each other and really don't want to be together. Since Holly is the bridesmaid and Chris is the best man, they now have to work together but it all becomes very embarrassing when those around them expect them to be a couple and the animosity between them only gets worse.
A really good movie (for being in this genre).
