An animated series of Christmas fairy tales that brings together the best of Czech animation and traditional stories and traditions. The main part of the series is the fairy tale O čertovi (About the Devil), based on the book of the same name by artist Pavel Čech. Santa Claus may be a nice old man who can do many things, but Czech winter belongs to St. Nicholas, Baby Jesus, carols, Christmas decorations, and, of course, devils and chimney sweeps! The guide through the fairy tales is the devil Florimón, whose story is the biggest and most important of all and concludes the entire series.
