Jacques Offenbach's operetta is a retelling of a mythical tale of Gods and mortals, and the battle raging between them. Married to Orpheus, Eurydice is embroiled in an affair with Aristaeus, really the God Pluto in disguise, who is so besotted with her that he lures her into the underworld for eternity. As Orpheus embarks on a mission to rescue her, Eurydice must choose between life with Pluto, an existence with Jupiter on Mount Olympus, or returning to her mortal life on Earth.
