Tia and Mike Baye never imagined they'd become the type of overprotective parents who spy on their kids. But their sixteen-year-old son Adam has been unusually distant lately, and after the suicide of his classmate Spencer Hill they can't help but worry. They install a sophisticated spy program on Adam's computer, and within days they are jolted by a message from an unknown correspondent addressed to their son: "Just stay quiet and all safe." Meanwhile, browsing through an online memorial for Spencer put together by his classmates, Betsy Hill is struck by a photo that appears to have been taken on the night of her son's death - and he wasn't alone.
