"El Florido Pensil" is a humorous reflection of the education of several generations of Spaniards from the 1940s to the 1960s. Based on the book of the same name by Andrés Sopeña, it evokes, from the present, his memories of that time: everyday school, local radio, Roberto Alcázar's comics, Thursday cinema with Franco opening swamps and "Yon Güein" chasing and killing Indians. Through the childish eyes of a child Sopeña (Daniel Rubio) and his schoolmates, we discover a way of understanding the world, society and a Spain "of glories and flowery pensil", as the national anthem of those years used to sing.
