Three years later, Grace is released on parole and becomes the nanny of Luna, the daughter of Alex Hill, unaware that Luna is her own biological daughter. Alex, a multimillionaire who had a one-night stand with Grace four years prior, has never stopped searching for her. Mark and Amanda continue to conspire against them.
