Luis Estrada adapts the play 'The Dead', by Jorge Ibargüengoitia. The story was inspired by the real case of the sisters María del Jesús and Delfina González Valenzuela who ran brothels in Jalisco and Guanajuato.

After discovering how they trafficked, enslaved and killed dozens of women, they were baptized as Las Poquianchis, the most ruthless murderers of the 20th century in Mexico.
