One night during his regular rambles, Mérimée stumbles upon a mysterious woman who invites him home to her place. They enter a big, dark but luxuriously furnished room and they spend the whole night having dinner and talking. However things take a turn to the strange when the eery lady starts talking about death and tombs. Mérimée realises that his companion is not an ordinary woman and that he is in danger. Will he get himself out of there alive or will Xélucha drag him with her to the underworld?
