A portrait of a couple, living in poverty and prostitution. Couple is joined by a second woman, and problems escalates.

El Negro and Mabel live in a poor, filthy suburb of a Latin American city. El Negro forces Mabel to be a prostitute, but she resists. Even after he has had to kill an aggressive customer he still keeps giving Mabel to other men. Mabel seeks help from "the Man who speaks of God". El Negro meets another street girl and tries to get both girls to work for him, in spite of Mabel's fury. Mabel falls into a kind of religious dementia. El Negro is sent to jail where he hears that "the Man who speaks of God " has managed to get Mabel to work for him.—Víctor González
