Upon her release from prison, she relocates to Mexico City with the help of Padre Porres, adopts a new identity as "Bella," and begins to rebuild her life.

Marimar undergoes a transformation into Bella Aldama, a sophisticated socialite, and attends the opera with Gustavo, where she unexpectedly encounters her estranged husband, Sergio.

Marimar's campaign against the Santibáñez family culminates as she drives Renato into deep gambling debt, taking the deed to their ranch as collateral.

She reveals her true identity to everyone, claiming ownership of the ranch and renaming it "Hacienda los Abuelos," elevating her social status above Angélica's.

Despite Sergio's lingering love for Marimar, he ends their marriage in disgust over her actions and plans to marry his childhood friend, Inocencia del Castillo.

Inocencia successfully undergoes surgery to remove her tumor and, feeling grateful for her new lease on life, apologizes to Marimar for her past behavior.

Ultimately, Marimar and Sergio reconcile and remarry in a small church in San Martin de la Costa, bringing their journey to a heartfelt conclusion.

In Mexico, Nathalie Lartrilleaux remade Marimar in 2013 under the title Corazón indomable and Ana Brenda Contreras and Daniel Arenas starred as the protagonists.

[4][5] In 2015, Philippines' GMA Network remade the Mexican telenovela for a second time, with Tom Rodriguez and Miss World 2013 winner Megan Young playing the title role.
