Who is the real Mac McAllister? Dana is in love...again, with Mac, a gorgeous boy in town. Shelley and Faith are happy for Dana, at least at first, but there's something a little odd about Mac. Why doesn't he ever remember Dana's friends after he meets them? Why does he forget where he and Dana are supposed to go on a date? Is he just very absent-minded? One night, when Faith and Shelley see Mac with Pamela, when he's supposed to be with Dana, they start to wonder. Mac seems to be a boy with a secret, and the roommates want to find out what it is. When they do, Dana is in for the biggest surprise of her life...
