Dr. Phil welcomes back previous guest Heather and her daughter, Marissa, who was rebelling in dangerous ways, like stealing her mom’s car and smoking marijuana. Since their appearance, Heather says things have gone from bad to worse. She says Marissa has continued to steal her car, smoke weed, fail at school and get into fist fights with other girls – and allegedly has also tried to kill Heather by poisoning her with hydrocodone tablets.

Marissa denies she ever tried to poison her mother and says she was just joking around in her texts. Dr. Phil also welcomes back child behavioral psychologist Dr. Michele Borba who conducts a one-on-one session with Marissa to determine why she is lashing out in such a destructive manner. Will Dr. Phil be able to get through to Marissa? Tune in to find out!
