The protagonists in this documentary are the five elderly members of the Cuban musical group La Vieja Trova Santiaguera (The Old Troubadours) as they were filmed during their five-month European tour. At the end of their concerts they need to be helped, not because they were tired from playing music or from showing their dancing spirit, but because a set of stairs can represent too big a risk for their fragile bones. Their lightness and sensuality in playing the rhythms of the enchanting Cuban motifs conflicts only with their stiffness and pain in coming down from the stage. Being their average age of eighty, the members of La Vieja Trova Santiaguera recreate Cuban sound - the music that was to become salsa - with the dynamism and ineffable grace of their lives' experiences.
