In order to retrieve and deliver an antique charm before her best friend's wedding, maid of honor Sarah Carlton must fake being in love with her childhood nemesis, best man Ben Atkins. Maid of honor Sarah Carlton hasn't failed at anything since her high school science project was sabotaged by a relentless competitor. So, she'll do whatever it takes to make her best friend Jill's wedding absolutely perfect. That includes taking the next flight out of Sacramento to retrieve the panicked bride's cherished family wedding charm from her late grandmother's attic in Atlanta, Georgia.
Unfortunately, someone else has offered to come to the bride's rescue-best man Ben Atkins, the same man who destroyed Sarah's high school science project all those years ago. Now he wants to one-up her by retrieving the charm first? Sarah refuses to let that happen. The race is on.
When Sarah and Ben arrive in Atlanta, instead of finding the wedding charm there's a letter from the bride's grandmother directing the bride and groom to complete a series of tasks in order to prove their commitment to each other. With the wedding only two days away, Sarah and Ben must join forces by pretending to be the bride and groom in order to earn the wedding charm. Should be a cinch. After all, how hard can it be to fake true love for forty-eight hours?
