A portrayal of Joaquín Díaz, one of the most important figures in the musical and cultural terrain, although his broad work is often unknown in its full extent. Commonly referred to as “the Spanish Pete Seeger”, the film rediscovers this precursor of the folk movement in Spain who in the 1960s also sang in Basque, Catalan, Galician or Asturian. When he was at the top, he chose to retire from public life and moved to a small medieval village where he continues to work tirelessly in order to recover folklore and memory that, without his effort, would have disappeared. Relevant musicians such as Kepa Junkera, Marina Rossell, Paco Ibáñez, Amancio Prada or Martirio speak about his legacy and influence in recovering the musical past.
