Prom night is fast approaching and Eric gets a motel room as part of his "spontaneous" plan to "do it" with Donna on the big night. When Jackie finds out that Kelso asked slutty Pam Macy to prom, she gets Hyde to take her out of pity. Fez wants to take his pretty English teacher to the prom. As for the adults, they struggle with how to respond to Midge's idea for her future career.

Eric finds a brochure for a nice motel and plans a romantic weekend with Donna, who's glad for the chance to get away from her feuding parents. Both lie about their whereabouts to their parents. But the lie blows up in their faces when they learn who their neighbors are at the motel. Meanwhile, Kelso thinks that he's not a man any more because he can't perform with Pam Macy.

Eric is distraught after his break-up with Donna and wishes that they never kissed in the first place. As soon as he utters this wish, a guardian angel appears to teach Eric that it's better to have loved and lost than to have never loved at all. The angel takes Eric on a journey to the future -- the '80s -- to show him how everyone's lives would've turned out if he and Donna never got together. Eric remains unconvinced that the pain of his break-up was worth it, until the angel shows him all the wonderful memories he would have never had.
