Charmed: From Fear to Eternity on AllMovie

Every 1,300 years, the "Demon of Fear," Barbas (Billy Drago, in his first series appearance), emerges from the Underworld, intent upon scaring all good witches literally to death on the occasion of Friday the 13th (significantly, this episode originally aired on Friday, February 13, 1999). Receiving an ominous warning from a very reliable source about Barbas' impending return, the Halliwell sisters prepare to do battle against the demon -- while Prue (Shannen Doherty) struggles to overcome an inner demon of her own making. Even with all this activity, Piper (Holly Marie Combs) finds time to inaugurate another romance (or at least, attempt to do so), while Phoebe (Alyssa Milano) again has trouble adjusting to a new job -- and this one is very important, not only to her but to her sisters.
