Lucía was a loving and devoted wife to Daniel Herrera. They lived together in an elegant home in Querétaro, along with his father, Don Rafael Herrera, an elderly man who had suffered a stroke and was left completely paralyzed.

He could not speak.
He could not move.
He could only look… and breathe.

Before they married, Daniel had been very clear with her.

— Lucía… I love you more than anything. But you must promise me one thing.
Never enter my father’s room when I’m not home.
Never try to bathe him or change him. That’s what his private nurse is for.
It hurts my father to be seen vulnerable by others.

Lucía was taken aback.

— But I’m his daughter-in-law… I want to help…

— No, Daniel replied firmly. Respect him. If you break this promise… our family could fall apart.
