The first volume of the series of books about mysterious creatures that eat socks won both the Magnesia Litera and the Golden Ribbon Award and has been translated into a number of languages including Spanish and Polish. So far three books by author, Pavel Šrut (who received the State Award for Literature in 2015), and illustrator, Galina Miklínová, have been published in the bestselling series. Šrut and Miklínová also wrote the screenplay for the upcoming family film.

The synopsis of the film from the official website:

Against the backdrop of a gangster story involving two feuding gangs of oddsockeaters, representing a clash between two generations and two sets of values, we are introduced to the world of the oddsockeaters. Pavel Šrut, joint screenplay writer and author of the original book, points us towards the similarities between their world and the human world, with the humour for which he is well known and without the connections ever seeming forced.
