The series takes place during the years leading up to the year 2000, and follows offender profiler Frank Black (Lance Henriksen), a law enforcement consultant with the ability to see inside the mind of criminals, working for a mysterious organization known as the Millennium Group. Despite premièring with impressive ratings, viewership declined throughout its three-season run, and it was finally canceled by Fox in 1999 after a total of sixty-seven episodes.
The show centers on FBI special agents Fox Mulder (David Duchovny) and Dana Scully (Gillian Anderson) who work on cases linked to the paranormal, called X-Files. In this episode, an associate of the Millennium Group, which believes the apocalypse will happen on the new year of 2000, resurrects the dead for use in the bringing about of the apocalypse. As a result, Mulder and Scully have to ask the help of criminal profiler Frank Black (Lance Henriksen), a man who has former experience with the Group, for assistance.
The episode serves as a crossover with the series Millennium, and was meant to bring closure to the recently-cancelled series. The writers had a difficult time coming up with a story that would successfully allow Frank Black and Mulder and Scully to cross paths. Lance Henrikson later expressed disappointment with the episode.
