The series stars Angélica Rivera, Jorge Salinas, Alejandra Barros, César Évora, Patricia Navidad, Adriana Fonseca, René Strickler and Alma Muriel.

Atilio is the owner of the mine; a powerful man with a strong character who becomes cruel when someone opposes his will and who keeps a secret that eats away at his soul: Mariana is not his daughter and what he feels for her is far from being paternal affection.

Marcia (Angélica Rivera), the youngest, is arrogant and vain, harsh with the miners and with a cold heart that has never known love, until in town appears Ignacio Lugo (Jorge Salinas), a young and attractive journalist who has arrived at the place under a false name, in search of his roots.

Furious and spiteful, Marcia informs her brother of the marriage and Atilio is determined to have Ignacio killed, without knowing that the man he is sentencing to death is his own son, the product of an affair with Lucrecia (María Rojo), the owner of the town’s restaurant.

Mariana's story is a heartbreaking and exciting tale; a complex and surprising plot of intrigues and dark secrets that dominate the life of a small mining town full of unforgettable characters, superstitions, rumors and legends.
