Documentary on several of Mercedes Sosa's performances at different places in the country, and the revival of popular music in the early '80s. The Argentine folk singer Mercedes Sosa was banned in her native land for many years because of her stance against totalitarianism, yet her excellent voice and popular songs kept her name alive and gave her a worldwide reputation. When the ban was lifted she came back to Argentina and sang in soccer stadiums because no other arena was large enough to hold the cheering, chanting crowds. Other than scenes from these concerts, this documentary includes interviews with Sosa and clips of her working in the recording studio and answering reporters' questions at press conferences.
