Aria has been cordially invited to the wedding of the century . According to her mom . Her older sister is finally marrying her high school sweetheart and she couldn't be any happier. Until she realizes she isn't just the Maid of Honor but the Best Man is none other than her good for nothing ex boyfriend . The man that ruined all other men for her and not in a good way . Unfortunately replacing the best man is out of the picture since he is , afterall, the groom's brother . Worse yet , he won't be coming alone . He's bringing his fiance to the wedding, the same girl you caught him cheating on you with, not more than 6 months ago. You know you can't not show up at the wedding , so you cook up a plan to find a fake boyfriend. You think about hiring an escort but shake that thought because you really don't have that kind of money to pay someone for a week. Your bestfriends suggest doing a little swiping and maybe convince the guy to help you out with your dilemma. What happens when you do an accidental swipe and the man you connect with is THE ONLY man who agrees to your hair brained idea?
