When Matt receives an invitation to high school best friend Ryan's wedding he's surprised--especially that Ryan is marrying a woman! Matt plans to rescue his former love from whatever "she-devil" has trapped him into this huge mistake. On the other hand, Ryan's perky fiancÃ© Alex takes quite the liking to Matt. Is she very cunning, disarmingly ditzy, completely adorable--or all three? As Matt tries to rekindle the old flame, Ryan is intent on putting out any sparks. Ryan dismisses their old romance as just a high school thing, but Matt realizes Ryan may still be the love of his life. All the while, Matt must deal with "his new best friend" Alex, the two families, and a hometown he thought he'd left entirely in the past.
