A horror anthology about Christmas. A collection of 24 films that take a look at the dark side of the festive season. 24 international directors from all over the world (Isaac Ezban being not only the only Latinamerican but also the only Mexican in the anthology) with the most diverse ideas and styles; linked by short animated segments that deal with the Advent calendar itself. Isaac Ezban and Red Elephant Films´s contribution, VILLANCICOS, is a surprisingly twisted and fcked-up that uses the classic Christmas carols to reflect on some of the darkest themes of this festivity: sickness, a family falling apart after the loss of one member, and Ezban´s trademark theme, the passage of time.
