Thirteen million children will be bullied in the U.S. this year. Dr. Phil examines a high school incident that involves lawsuits, death threats and both sides feeling bullied. Sixteen-year-old Katie says her classmate Nick turned against her and started recruiting people to join a "Kill Katie Klub." She says the taunting by her classmates escalated and forced her to quit school. Katie's mom, Giselle, says her daughter — once, a popular cheerleader with good grades — is now homeschooled and has lost everything. Giselle says her attempts to remedy the situation with parents and school officials fell on deaf ears, so she was forced to go to the police, resulting in backlash from her community. Giselle says she wants Nick and his parents, Michelle and Daniel, to take responsibility. Michelle and Daniel speak out exclusively to Dr. Phil, insisting that Nick was just making a joke about starting a “Kill Katie Klub,” and that it went no further.
