She served 13 months in jai, and is now permanently on the sex offender registry. Erin, now 22, says she's struggling to let go of the anger and resentment she still feels for her mother. Face to face on Dr. Phil's stage, will Lisa take responsibility for not taking action? And, can Dr. Phil help Erin find forgiveness? Then, find out why Lisa's 14-year-old daughter may now be in need of her mom's protection, and if Lisa is up to the task. This program contains strong sexual content. Viewer discretion advised.
