Synopsis: Bob Wilson, while working on his thesis, is visited by "Joe" who appears in his room via a Time Gate. Joe is insistent that Bob go through the Time Gate, and when he refuses, Joe helps him through the Gate himself. When he awakens, he finds himself with Diktor, at least 20,000 years in the future.
