On this website you will find one of the virtual fourth seasons for the series. FK4 is conceptually predicated on the idea that the series was never cancelled in 1996.
The season premiere has been designed as a series premiere.
So, if you like genre TV but do not know Forever Knight, FK4 is just as accessible to you as it is to long-time fans.
And, if you are a long-time fan, then FK4 continues the story...as it might have been told had the show not been cancelled.
