''La madrastra'' (The Step-Mother) is a 2005 Mexican [[SoapOpera telenovela]], based actually on a Chilean one from TheEighties. It stars Victoria Ruffo as María Fernández Acuña, an [[TheIngenue ingenue young woman]] who, due to a gross MiscarriageOfJustice, is incarcerated for twenty years for the murder of her friend Patricia, which she did not commit.

After being released from jail, María returns to Mexico City with three purposes: to exact {{revenge}} on her husband and friends who abandoned her to the Aruban justice system, to find Patricia's real murderer, and to be reunited with her children, who believe her to be deceased and, once she marries their father, think she is their stepmother.

!!This show provides examples of:


* CaughtOnTape: Patricia's murder is caught on tape by a MagicalSecurityCam.
* CreepyCrossdresser: Shockingly not Bruno, but [[spoiler: Demetrio]]
* CreepyChild: A television special that narrates the end of the story, ''Años después'', 10 years after the events of the series, with all the young couples now with children. For some reason, [[spoiler: Angelito, Angel and Alma's son, turned out to be an evil kid, easily manipulated by Demetrio, his grandfather, into doing evil things to his family, as a personal vengeance against them. And the boy enjoys it. Weirdly enough, the moment he sees Demetrio fighiting against Esteban, he realizes that he's evil, he made him do evil things and has a HeelFaceTurn by the end of the show]].
* DeusExMachina: The convenient video tape of Patricia's murder, which despite ostensibly being home footage and not from a security camera, [[MagicalSecurityCam somehow involves numerous camera angles and cuts between the principal actors.]] Let's not even start on who is supposed to have recorded the footage...
* DrivenToSuicide: [[spoiler: Alba kills herself in public while claiming that Esteban is the one behind Patricia's death.]]
* EntitledToHaveYou: [[spoiler: Alba believes she's entitled to have Esteban, since she cared for him during all his life and "knows him better" compared to Maria. She doesn't take Esteban's feelings into account, much less the fact she's his aunt.]]
* FamilyRelationshipSwitcheroo: Ángel grows up believing that the entirely fictional "Montserrat" is his mother before learning that [[spoiler: his great-aunt Alba is his mother, only to finally discover that his other great-aunt Carmela]] gave him life.
* {{Guyliner}}: Bruno. And how...
* MonochromeCasting: Despite the fact that the vast majority of the Mexican population is of [[https://en.wikipedia.org/wiki/Mestizo mestizo]] descent, the entire main cast is noticeably paler than average.
* MiscarriageOfJustice
* NotGoodWithRejection: [[spoiler: After Esteban rejects his aunt's romantic advances, she commits suicide after claiming that he's Patricia's killer. Out of petty revenge.]]
* ParentalAbandonment: [[spoiler: Bruno and Fabiola abandon their newborn son after he is born with severe physical deformities due to their drug abuse. Demetrio and Carmela/Alba also abandon their son Ángel and allow Esteban to raise him as his own.]]
* RedemptionEqualsDeath: [[spoiler: Carlos and Ana Rosa.]]
* RichBitch: Especially Fabiola, Patricia, and Alba, but also Daniela and Ana Rosa to a lesser degree.
* SerialKiller: The mysterious culprit.
* TheUnfavorite: El Pulpo, whose WickedStepmother favored her natural son Servando.
* TookALevelInDumbass: Almost every character in the whole series, right a month or so before the end, from the main character to the villains. By this time, a new telenovela was already announced, so people were actually already waiting for this story to finally come to an end. The new telenovela finally aired, but ''La Madrastra'' didn't end yet, it only took a change of schedule.
* VillainousIncest: Alba's burning love for her nephew, Esteban, whom she raised following the deaths of his parents when he was young, brings this trope disturbingly close to ParentalIncest and EntitledToHaveYou, too.
* WakeupMakeup: Largely subverted. Fabiola, for example, is featured in a number of episodes sans her normally heavy make-up after emerging from the shower or before going to bed (cf. episodes 41 and 90, especially).
