Seventeen-year-old Taylor is having a tough time in high school after the controversial death of her father in a drunk driving accident. Her widowed mother Allison, a cop with the local police department, is doing her best to balance her demanding job and raise Taylor on her own. One night, Taylor gets a chat request on her computer. It comes from a user calling himself "TRUTH&LIES," who claims to "know the truth" and ends the conversation with an ominous "I know." Over the next few days, Taylor gets more messages from "TRUTH&LIES," and soon realizes she's not the only one. Taylor now must team up with her ex-best friend Hannah, ex-boyfriend Zach, confidant Barb, and the cute new guy in school Cody-- who all have secrets of their own-- to discover the identity "TRUTH&LIES" before their secrets go public... or worse.
