It's Día de los Muertos, and your little brother Miguel has just dragged you into the mausoleum to steal a guitar. Ernesto de la Cruz’s guitar. The next thing you know, you're walking unseen among the living—and very much trapped in the Land of the Dead. Now separated from Miguel, you’re alone, confused, and face to face with your long-lost ancestors, who are both relieved and annoyed by your sudden appearance. Time is running out to reunite with your brother, unlock the truth of your family’s past, and discover the real story behind your great-great-grandfather... before sunrise.
