Ray and Deena say that three years ago, after Deena had an affair and they divorced, their 16-year-old daughter, Summer, went from a straight-A student to a violent and out-of-control teen. The parents say that Summer shoplifts, uses drugs, gets into physical fights with friends and family, dresses provocatively and lies about her age to date much older men. They also claim that she has run away from home at least 15 times -- including a month-long ordeal in Las Vegas, when they say Summer lived on the streets, abused drugs and panhandled for money. How does Summer explain her behavior? Hear why she says she had no choice but to run away to Vegas -- with a near-stranger. And, how do Ray and Deena respond? Has the contention between them compromised their ability to parent Summer? Dr. Phil weighs in and offers the fractured family advice for moving forward. Will the parents be willing to come together to get Summer back on track?
