It's 1985 and rock-star wannabe Robbie Hart is New Jersey's favourite wedding singer. He's the life of the party - until his own fiancée 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. Only trouble is Julia is about to be married to a Wall Street shark, and unless Robbie can pull off the performance of the decade, the girl of his dreams will be gone forever.
