When Eric finds out that Casey is taking Donna to a motel, he decides to show up to make sure she doesn't do anything she'll regret. Bob's divorce from Midge comes through, he mentions marriage to Joanne, who totally freaks out. Naturally, Red and Kitty are called upon to advise their neighbors, but unfortunately they aren't offering the same advice. And Kelso stalks Jackie at the mall to prevent her from kissing anyone else.
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.
