Cuidado con el ángel

María de Jesus, better known as Marichuy, is humble young girl living with Candelaria, a laundress who gave her a home when she was wandering on the streets. Candelaria is like a mother to Marichuy because she never met her biological mother as she was left in an orphanage when she was a baby. The abandonment has led her to believe her mother never loved her. Marichuy's biological mother, Cecilia Velarde, entrusted her baby to a priest, named Father Anselmo, who took the baby to an orphanage, after she thought she was dying. Now, she regrets making that decision and has spent most of her life searching for her lost child.

Marichuy also hides a horrible secret. At the age of 14, Marichuy ran away from the orphanage, and began to live on the streets, doing her best to survive. One night, she was attacked by a drunk man. She cannot seek justice for what happened to her because she did not see the man's face very well since she was attacked late at night. This experience, as well as having terrible recurrent nightmares, leaves her with a deep resentment towards men.

Juan Miguel San Román is a prestigious psychiatrist who has dedicated his time to the rehabilitation of young rebels and criminals. This serves as a distraction from his failing marriage to his wife Viviana and a horrible crime he committed during his youth while he was drunk. Once again, destiny brings Juan Miguel and Marichuy together when she is arrested with a group of friends. From that point, he vows to help Marichuy and he takes her to Judge Patricio Velarde's home, a very strict, heartless man, who is also her biological father.

As soon as Marichuy steps foot into the house, Cecilia welcomes her with open arms, but Judge Patricio despises her from the start due to her lack of manners. She also is not well received by the Velarde's daughter, Estefanía and her aunt, Isabela. Estefanía is not the Velarde's real daughter. She and her aunt schemed up a plan to have Cecilia believe that she had found her daughter, that way, they would both move into their mansion and not live in poverty anymore.

Eventually, Marichuy and Juan Miguel fall in love and get married. On their wedding night, Marichuy has the same nightmare, but this time she is able to recognize the man's face who is Juan Miguel, the love of her life. Marichuy runs out of the hotel room, devastated. Juan Miguel runs after her and tries to calm her. She apologizes but Juan Miguel confesses that her nightmares were, indeed, true. This enrages Marichuy and she runs off again and takes a bus back to Mexico City.

The next stage of the novela is Juan Miguel constantly begging Marichuy to forgive him and she rejecting him. She later finds out she is pregnant and decides to forgive him. Turns out however, that Juan Miguel's first wife Viviana is still alive and she returns pretending she lost her memory. Juan Miguel thinking Marichuy came to beg him for a divorce instead of coming to forgive him, screams about Viviana's return before Marichuy has a chance to speak. Devastated Marichuy leaves and hides out in a farm for a while.

Then begins the third stage of the novela. This stage consists of pregnant Marichuy hiding out in a farm of guy name Omar (better known as Leopardo) while taking a fake name of Lirio. While she is in the farm Leopardo falls in love with Lirio (really Marichuy) and she agrees to marry him, and she has Juan Miguel's kid. Everything appears to be going well for Marichuy. Meanwhile, Juan Miguel is missing Marichuy and is taking care of his supposedly memory-lost wife, Viviana. He hires a nanny, Blanca, to take care of his daughter Mayita. Blanca turns out to have multiple personality disorders and her other personality, Ivette, stabs Viviana, killing her. Juan Miguel takes the blame for the murder trying to help Blanca. Well Marichuy sees of his imprisonment in the newspaper and decides to go back, standing Leopardo up before their wedding, to help Juan Miguel. However, Juan Miguel gets freed since Blanca confesses it was her (or at least kinda her since it was her other personality Ivette). He decides to marry Blanca in order to help her and make her feel supported.

Marichuy gets back but discovers Juan Miguel is engaged to Blanca and is heartbroken. She knows she lost Leopardo for coming back to help Juan Miguel so she doesn't know what to do and decides to pursue acting (having previously acted before hiding out in the farm). She starts working as a theater actress to support herself and her child, as well as Candelaria. Leopardo comes looking for her and turns out he is friends with Juan Miguel and they talk about their great love for a woman not knowing it is the same woman. At some point they discover Marichuy and Lirio are the same woman and Juan Miguel discovers he has a son with Marichuy. Many things happens but at the end of this stage of the novela Leopardo and Blanca get together and Marichuy goes blind after a bullet hits her in her head, luckily doesn't die.

Unfortunately, this is not enough for Marichuy and Juan Miguel to finally get together. Many other things happens in the novela, like; Marichuy losing her kid, Marichuy finding out she is a Velarde and forgiving her parents (after many episodes of hating them), Juan Miguel becoming an eye surgeon, Juan Miguel pretending to be someone else to be close to Marichuy since she is blind, and Juan Miguel giving Marichuy her sight back through a surgery. At the end, Juan Miguel and Marichuy finally get married again living happily ever after with their two kids.

The show was adapted to a Vietnamese drama called "Tóc rối" (English: Tangled Hair).
