Celestino Pintamonas is a down-on-his-luck artist who is going through financial difficulties. Son and grandson of great renown painters, he is forced to even accept brush painting to make a living. But fate changes one day. He is hired by the most outlandish circus: the Circus of the Big Lopez. Celestino will be in charge of painting all the members of the troupe (Clowns, trapeze artists, tightrope walkers, jugglers…..) because, due to a terrible curse, they have become invisible!!! There is no greater misfortune for a circus than not being seen by its audience. Celestino will paint their faces, arms and chests to keep the show going on. But, together with his inseparable dog Lola, he has to free them from the terrible curse that has befallen on the circus.
