Petitet is a Catalan gypsy pursuing a dream. Former musician and son of one of the "palmeros" (hand-clapping performers) of the mythical Peret, he suffers from a rare chronic disease that causes acute muscle weakness. In his fifties, he wants to fulfil the promise he made to his mother before she died: to take Catalan rumba to the stage of a great theatre. The dream begins to come true when a band of gypsy musicians (talented but undisciplined) gather together to try and play alongside a great symphony orchestra at the Gran Teatre del Liceu!
Petitet is aware that in order to fulfil his promise, he will have to overcome many obstacles: with limited economic resources, he will need to do little jobs, such as buying and selling scrap metal. He doesn’t have any relevant contacts in the institutions and it’s not easy for him to gain access to the musicians from large symphonic orchestras. Despite all the obstacles and diminished abilities due to his illness, he realizes that there are many (gypsies and non-Roma) who have already decided to remain loyal to him and make his dream come true.

La rumba es mestizaje. Y el cine documental, también: en 'Petitet' existe ese olfato del reportero curtido en mil batallas, sí. Pero también brillan una épica más propia de la ficción.— El país
