When Catalina (Carolina Gaitán) is born, her father Albeiro Marín (Fabián Ríos) and mother Hilda Santana fear she will share her late older sister's fate, as most of the young women in their neighborhood have historically become involved with prostitution and organized crime.

In order to protect their daughter, Albeiro and Hilda paint a yellow boundary line outside of their home, forbidding Catalina from crossing it until she turns 18.

After witnessing an attack upon Hernán Darío by Yésica Beltrán's (Majida Issa) bodyguards, Catalina crosses the yellow line to defend him.

Catalina is sent to an institution for juvenile girls , where she is beaten and abused by the fellow inmates and guards and nearly drowned under Yésica Beltrán's (Majida Issa) orders.

Hernán Darío is beaten and humiliated as well until Yésica and her daughter Daniela (Johanna Fadul) force him to work for them, threatening to hurt his mother, his in-laws and Catalina.

During all the years of her supposed disappearance, she made her life next to Santiago Sanín (Roberto Manrique) a doctor with whom she had two children Mariana (Stephania Duque) and Sebastián (Johan Esteban Díaz).

[22] The character of Yésica Beltrán, La Diabla, was originally interpreted by María Fernanda Yepes in Sin senos no hay paraíso, but she did not return for the sequel due to scheduling conflicts and personal reasons.
