Having stolen the "god-hood" of Aphrodite (Alexandra Tydings), the mad Roman emperor Caligula (Alexis Arquette) is now immortal. Under orders from the Archangel Michael (Charles Mesure), Xena (Lucy Lawless) attempts to end Caligula's rampage of terror, and to find some way of revoking his immortality. Such an undertaking requires a disguise -- which is why Xena ends up posing as famed female gladiator Mosca, with Gabrielle (Renee O'Connor) as Mosca's advance person, Cynda of Thrace. ~ Hal Erickson, Rovi
