The story of a group of young Argentine musicians who want to start a tango orchestra school but they need the "old guard" - the true tango maestros - to lead them, to transmit and pass on their teachings, so the young musicians are racing to learn and preserve the elegant and nuanced music played by the legendary Golden Age tango orchestras of Buenos Aires in the 40's and 50's before the aging musical icons pass on.
