After moving the hearts of Hades and Persephone with the sadness of his lyre, Orpheus is granted the opportunity to take his wife Eurydice back to the world of the living, with one condition: he must not look back until they’re both under the sunlight.

It sounds easy enough, so Orpheus starts climbing through the dark tunnels of the Underworld, hoping to finally reunite with Eurydice. But when he hears anything but the echo of his own footsteps, a question starts to haunt him:

Is Eurydice really behind him?
