Plot summary
Tempus ( Lane Davies ) returns to Metropolis and kidnaps Lois taking her to a parallel universe where things are very different than her universe; she died a couple of years ago before Clark came to work at the "Daily Planet", Jimmy is the owner of the Daily Planet, Perry is running for Mayor against Tempus and most importantly, there is no Superman. H.G. Wells ( Hamilton Camp ) helps Lois to remember her previous encounter with Tempus and also go back to her universe. In the meantime, Lois has to convince Clark Kent of this parallel universe to become the hero he has always been and manage to expose Tempus before he kills Perry and becomes Metropolis' Mayor. Everything works out fine and Lois, with Wells' help, has to now return to her Clark Kent and get ready for her wedding.
