In this musical drama, a tango tribute set in Buenos Aires of the '30s, factory worker Juanita (Aitana Sanchez-Gijon) goes with musician Gustavo (Juan Echanove) who plays in a tango combo with singer Renzo (Dario Grandinetti), known for his resemblance to famed tango superstar Carlos Gardel (who died in a 1935 plane crash). Juanita ditches Gustavo for Renzo, and when Gardel is unable to do a radio commercial, a substitution by Renzo brings enough fame to propel the group on a Latin American tour. Renzo visits a Colombia hotel where Gardel is staying, and when Gardel returns to Argentina, Renzo once again serves as a replacement, this time in a live performance -- but fate steps in as Renzo heads home.
