Saint Ambrose Prep is a place where the wealthy send their children for the best possible education, with graduates who become future lawyers, politicians, filmmakers, and CEOs. Traditionally a boys-only school, Saint Ambrose has just enrolled one hundred and forty female students for the first time. Even though most of the kids on the campus have all the privilege in the world, some are struggling, wounded by their parents' bitter divorces, dealing with insecurity and loneliness. In such a heightened environment, even the smallest spark can become a raging fire. One day after the school's annual Halloween event, a student lies in the hospital, her system poisoned by dangerous levels of alcohol. Everyone in this sheltered community are left trying to figure out what actually happened. Only a handful of students know the answers and they have vowed to keep one another's secrets. As details from the evening emerge, no one at Saint Ambrose can escape the fallout of a life-altering event.
