S1·E19 The Lure of the Lyre

A young minstrel, Orpheus, and his girlfriend, Eurydice, lure Hercules, Iolaus, and Lilith into what they claim is a place where the party never ends, run by Bacchus, the God of Partying and Good Times. In reality, they soon learn, it is the realm of the Bacchae, the vampire-like followers of Bacchus, which they discover only after Lilith has been bitten and is slowly changing into one herself.
