Joan Manén (Barcelona 1883-1971) was considered the world's best violinist during the first half of the 20th century. He was a self-made violinist; he did not belong to any school nor was he instructed by any of the great masters of the time. 45 years after his death, his name is barely known. In 2011, a group of musicians started the Joan Manén Association. This documentary is the result of following their steps during four years, as they tried to reclaim the legacy of this great forgotten figure through the dissemination of his work, the search for missing scores, the restoration of his instruments, by organising concerts, etc.
