Tlalpujahua, Mexico is the Christmas decoration capital of the world, where every day feels like a holiday. As Elena, a factory worker, loses her festive cheer, a sentient computer begins to ask questions about the meaning of Christmas.

Linda brings her new boyfriend, Kevin, home for the holidays. He's kind and considerate, but here's just one catch: he happens to be an immortal, blood-sucking vampire, with an eons-old rivalry with Santa Claus - and it's Christmas Eve.

Noé works at the record shop. Charlotte works at the bookstore. As they struggle to express their true feelings for each other, life begins to imitate art. We find that small gestures can become magical, with a little help from Christmas.
