María Hernández is a young, humble, uneducated dreamer, who lives with her godmother Cacilda on the outskirts of Mexico City and works as a picker of recyclable material in a landfill. On the day that María turns 15, her godmother dies, who on her deathbed, asks Father Honorio to find a place where her goddaughter can work and live. Maria is welcomed by businessman Fernando De la Vega, one of the most influential and richest men in the country. He teaches María manners and welcomes her as a family member, although his wife Victoria and Carlota, one of the household's maids, despise María upon meeting her.
