It's 1985 and rock-star wannabe Robbie Hart is New Jersey's favorite wedding singer. He's the life of the party, until his own fiancee leaves him at the altar. Shot through the heart, Robbie makes every wedding as disastrous as his own. Enter Julia, a winsome waitress who wins his affection. As luck would have it, Julia is about to be married to a Wall Street shark, and unless Robbie can pull off the performance of a decade, the girl of his dreams will be gone forever.
