Musical documentary directed by German Kral telling the story of legendary tango dancers María Nieves Rego and Juan Carlos Copes. Rego and Copes met when they were only teenagers and went on to dance the tango together for almost 50 years. Their relationship rocked back and forth between love and hate throughout the years, but they always held their passion for the art of dance. Here, Rego and Copes speak candidly about the story of their lives and their tales are transformed into spectacular dance performances by a group of young dancers and choreographers from Buenos Aires. The documentary also offers introspective interviews with both Rego and Copes, as well as footage which charts their careers in dance through the years.
