Marimar, a poor yet innocent girl, lives with her grandparents in a beach hut in San Martin de la Costa, where she crosses paths with Sergio, the son of a wealthy ranch owner. After stealing food from the Santibañez's garden, she is caught by Nicandro, the Hacienda foreman, who nearly assaults her—but Sergio intervenes, leading to their blossoming romance and marriage. However, their union faces opposition, particularly from Angélica, Sergio's stepmother, who looks down on Marimar for her simplicity and lack of formal education.
Angélica schemes to ruin Marimar, humiliating her at a party with a ridiculous dress while Antonieta falsely accuses her of an affair with Chuy, a Ranch worker.
After Sergio leaves for a business trip, Angélica tricks Marimar into fetching a necklace with her teeth, then frames her for theft, leading to her arrest. She later orchestrates the burning of Marimar's grandparents’ hut and forges a letter in Sergio's handwriting, claiming he never loved her.
Scarred by betrayal, Marimar seeks revenge, adopting the identity of “Bella” with Padre Porres' help after her release from prison and relocating to Mexico City to rebuild her life.
Marimar's life takes a turn when she works for Gustavo Aldama, who has been searching for his daughter,María del Mar, and with his sister Esperanza's help, she refines her skills and appearance. Her journey becomes even more profound when she discovers she is pregnant with Sergio's child and later gives birth to their daughter, Crucita.
Marimar reinvents herself as Bella Aldama, a sophisticated socialite, and unexpectedly reunites with Sergio at the opera, fueling her desire for revenge against him and the Santibañez family. After revealing her true identity to Gustavo during a confrontation with Bernardo Duarte, Gustavo suffers a fatal heart attack, leaving Marimar to inherit part of Club Valle Encantado. She manages the club alongside her cousins until Bernardo sells his share to Rodolfo San Genis, a wealthy admirer, further complicating Marimar's tangled relationships. As she catches the interest of Governor Fernando Montenegro, his daughter Natalia falls for Sergio, turning Marimar into her rival.
Renato kills Nicandro after catching him attempting to assault Angélica, then flees to Valle Encantado, where Marimar manipulates Brenda into seducing him, leading to his downfall in alcohol, gambling, and debt. Seeking revenge, Marimar forces Angélica to retrieve promissory notes from the mud with her teeth before selling her share of Valle Encantado and returning to San Martin de la Costa. Meanwhile, Antonieta leaves her wealthy lifestyle for Chuy, and Sergio marries his childhood friend, Inocencia del Castillo, only for Marimar to crash their wedding. Angélica, tormented by Nicandro's twin brother investigating his death, faces the consequences of her past actions.
Angélica suffers a fatal car accident on her way to Valle Encantado, and, consumed by hatred, demands that Marimar's house be burned before she dies. Meanwhile, Inocencia, troubled by Sergio's lingering attachment to Marimar, collapses during pregnancy and is hospitalized, where she safely delivers her child but is diagnosed with a brain tumor. During her hospital stay, she strikes a deal with Marimar: if she survives surgery, Marimar must stay away from Sergio; if not, Marimar must marry him. Despite this, Marimar vows to forget Sergio, regardless of Inocencia's fate.
Marimar starts a relationship with engineer Adrián Rosales, while Inocencia, grateful for her recovery, apologizes to Marimar and vows not to interfere with her and Sergio, as long as he supports their child. Meanwhile, Renato regrets his past actions and seeks forgiveness for both himself and Angélica.
Padre Porres helps Sergio understand Marimar's pursuit of revenge, allowing them to confront their unresolved feelings over a betrayal that never occurred. With newfound clarity, they reconcile and remarry in a small church in San Martin de la Costa, bringing their journey to a heartfelt conclusion.
