The second season of Señora Acero begins with Sara behind bars. She has been waiting five years for a sentence in her case when an attack on her son Salvador (Michele Duval), now a teenager, drives her into a desperate attempt to escape Puente Grande prison. This feat ends in tragedy and an extended sentence for another 25 years. It won’t be long, however, until her friend Aracely (Litzy) finds the key to her release.
