Joan Ximénez el Petitet is a Catalan gypsy who pursues a dream. A former musician now —a percussionist, son of Ramón el Huesos who worked with the mythical singer Peret—, and affected by a rare chronic disease, he wants to accomplish the promise he made to his mother before she died: to celebrate a rumba concert on the stage of the Liceu, a great theater in Barcelona, along with a big symphony orchestra.

An account of the personal and artistic life of the Spanish singer Peret (1935-2014), the artist who imaginatively mixed various musical styles, such as mambo, tanguillo and rock, to create the gypsy rumba. An epic adventure, from a humble neighborhood of Barcelona to the biggest stages of the world.
