Decades later, Mia unplugs Sylvia's hospital life support, condemning the woman who raised her as a murderous homewrecker. Granted a miraculous temporal regression back to her violent marital home, Sylvia faces an agonizing challenge: she must survive Clive's rage without poisoning the soul of the child she loves.
