The Case of Evil

Back in 1982, Star Trek was riding high. The show's rabid fanbase and the general public had both loved that year's big science fiction blockbuster, Star Trek II: The Wrath of Khan, and were desperate to know what was coming next. HoustonCon, the annual science fiction convention in the biggest city in Texas, was looking to capitalise on that fandom and arranged for almost the entire cast of the movie to attend. Dubbed "Ultimate Fantasy," the con had everything: a one-act play written by Koenig that the Trek actors were to perform, a laser light show, and even a rotating Trek-logo-shaped stage. And then it all went terribly wrong.
