Cyberbully follows Taylor Hillridge (Emily Osment), a teenage girl who falls victim to online bullying, and the cost it nearly takes on her and her family. Taylor is a pretty 17-year-old high school student but a little awkward, and painfully aware of it. When her mom gives her a computer for her birthday, Taylor is excited by the prospect of freedom and the independence of going online without her mother always looking over her shoulder. However, Taylor soon finds herself the victim of betrayal and bullying while visiting a social website, and afraid to face her peers at school, including her best friend (Kay Panabaker), she is pushed to a breaking point. Taylor's mom, Kris (Kelly Rowan), reels from the incident and takes on the school system and state legislation to help prevent others from going through the same harrowing ordeal as her daughter.
