Framed for a crime she didn't commit, Isabel died leaving behind her little daughter. Ten years later, she awakens in another woman's body, with only one year left to live. But the world she returns to is even crueler. Her daughter is now married to the very man who murdered her, all in the name of revenge. With just one year, Isabel must find a way to save her daughter, no matter the cost.
