Jeanine and Nathan say they thought it would be mutually beneficial to have Jeanine's 70-year-old mother, Liz, live with them when she couldn't afford her building's rent increase. But Liz says she was not prepared for what she calls their "dirty home," which led to her complaining to others about the living conditions, and then led to CPS opening an investigation. Jeanine and Nathan then kicked out Liz. Liz claims that as a result of her daughter's actions, she is homeless and living in her car. Jeanine and Nathan say they have not spoken to Liz until seeing her at the show. Dr. Phil works to find out why exactly CPS was initially called and if something can be done about Liz's homelessness.
