Pecado de amor

Nun Belen works as a spiritual guide in a women's prison. Is a very understanding woman, possibly due to her past. At the past she was Magda, the star of the cabaret "The Mill of Twenty." She was attractive, young and admired by the public, she had it all, but three very different men end up marking her destination. A fate that is inexorably opposed to her happiness.
