Tango is not just a dance. On the Rio de la Plata, tango is a way of life. Tango belongs to Argentina--and in particular to cities such as Buenos Aires, Montevideo and Rosario, where tango is much more than simply a nostalgic echo of the past. Many of the grand old men and women of tango live here. They still perform and some of them have been doing so for almost eighty years. The documentary portrays some of these exceptional musicians,including creators of tango's classical repertoire and founders of a variety of styles and schools, as well as the members of bands and orchestras who found fame in the 1940s and 1950s, during the golden age of tango.
