Erin says that when she was 8 years old, her stepfather, "Mr. Dave," began sexually abusing her, and that she also watched him molest her friends. Erin says that despite telling her mother, Lisa, what was happening -- a claim her mother denies -- the atrocities continued until she confided in a teacher -- three years later. Erin’s stepfather was arrested and is currently behind bars, and Lisa was convicted of sexual abuse of a minor for failing to protect her daughter. She served 13 months in jail, 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.
