Robbie Hart is a wedding singer who can cover the latest hits, deliver the perfect toast to the bride and groom and even get Grandma on the dance floor. But when Robbie is dumped at his own wedding, he has a total eclipse of the heart and becomes the ultimate cynic. It's not until he meets Julia, a waitress, that Robbie starts to come around. However, Julia's about to get married herself, and unless Robbie can pull off the performance of a lifetime, the girl of his dreams may be gone forever.
