A comprehensive history of European Jazz, exploring the origins of the US-influenced Jazz clubs after the Second World War, the first steps independent of American jazz and the various changes of direction that have repeatedly occurred in European jazz in the search for that "own voice" that European jazz musicians have helped to form. Featuring the great masters of European jazz such as Chris Barber, Jan Garbarek, Juliette Gréco, Stefano Bollani and Till Brönner, to name but a few.

Starting from the present and the living environment of young jazz musicians, this energetic documentary explores the question of why jazz was able to conquer the Republic so quickly, survive the times of fascism despite all reprisals and carry off its final triumph after the war.
