The Legend of Tué Tué

Original title: La leyenda del Tué Tué

Alan, a young university student, is told the legend of the shapeshifter Tué-Tué, a being that disguises itself as a bird and whenever you see it you have to invite it to dinner. Not doing means death, but Alan does not invite the Tué-Tué when he sees it, so that night a strange figure knocks on his door.
