Jonny came to Dr. Phil begging for help because she claims her mom, Nancy, has become "delusional" and completely obsessed with what she calls a "secret hookup app." Nancy says people on the app use a "secret color code" and a "secret number system" to try to communicate with her for sex. Nancy claims these people will hold up the numbers 1 through 8 on their fingers to communicate different sex acts. Nancy says she feels in danger because wherever she goes, she sees people tracking her location using the "hookup app!" But Jonny says nobody is tracking her mom, and it's "all in her head." Is Nancy being tracked? Dr. Phil investigates. Don't miss it!
