The main character of the film is 12-year-old Miguel. The teenager lives in a Mexican village in a family of shoemakers and secretly dreams of becoming a musician. Secretly - because his family clan consider music as a curse. Once his great-grandfather left his wife, great-grandmother of Miguel, for a dream that no longer leaves in peace Miguel. Since then, the theme music in the family has become a taboo. Miguel finds between him and his favorite singer Ernesto de la Cruz, the late, a certain - yet unnamed - relation. The boy goes to his idol in the Land of the Dead, where he meets the souls of his ancestors.
