La Güera is the director of the "El Amanecer" rehabilitation center, where she is responsible for providing support to young people with drug addiction problems, following the "Twelve Steps" model. One day, La Güera's cousin asks her for help in admitting her young son Samuel to the center; La Güera goes to invite him to join the rehabilitation center. Samuel refuses and is taken there by force, which complicates his adjustment to the place. La Güera tries to encourage him and give him attention so that he can get used to his new surroundings. Everything seems to be going well when an armed group bursts in and takes several inmates, including Samuel. La Güera is forced to turn to one of her associates to get him back, revealing a dark secret.
