María is overwhelmed by guilt, but she decides not to share it with anyone. She tries to return to her routine, but she only has one name on her mind: Santiago Aguirre.
María, half aware of what it means to meet with Santiago's son, tries to find any excuse not to go to the date. Finally, motivated to confess, she goes to the meeting.
In one last attempt to be social, María attends a big party. In an attempt to be accepted, she makes a bad decision that humiliates her in front of everyone. She also receives a devastating call from Santa.

After a few weeks, María finds a job at the Tunnel of Terror at Parque de Atracciones de Madrid. However, she has to choose between her promise and her reinsertion. She turns to Gabriel for help.
After three years, María gets out of prison and has to face reinsertion. She tries to fulfill a promise she made to one of her prison mates, whatever it takes.
A wild road trip drags María down and leaves her with no chance at salvation. A mouthful of faith fills her heart again and she sees a sign to find Yasmín and fulfill her promise.
