A woman's voice says she was wife to Renzo Franchi and Carlos Gardel (1890-1935), Argentina's great tango singer. People say she's crazy. Her story unfolds. Buenos Aires, 1933: Juana Romero, a seamstress who lives for the music of Gardel, dumps her boyfriend Gustavo for Renzo, a singer who looks like Gardel. She insists that his trio performs Gardel's tangos, which leads to Renzo recording a Ford commercial when Gardel himself is overbooked. The trio, with Joanna in tow, goes on an ill-fated tour of points north. The couple breaks up: she goes home and he tries to get to New York. Fate steps in, and once again he's called upon to pose as Gardel. Then, legend and a bracelet take over.
