La flor de la ribera(1931)

Unlike most works of that era that revolved around tango, the fictional film tells the story of a young opera singer. Following in Ferreyra's footsteps, the film explores the streets of La Boca, the port, and the bar, with a marked realism even as the fictional narrative—a young fisherman becomes an international opera star, leaving her humble girlfriend behind—drives the action forward, culminating in a drama with an unexpected ending.
