An unlikely gang of teens go on the run to an island music festival, leaving behind their dysfunctional parents and the rules of the real world.

When Emily Parris exposes a secret society of teenage girls who have slipped out of the world of social media and into another world they've discovered in the woods at night. When she accuses the girls of committing sexually deviant activities, Emily sends the small American town into a atmosphere of hysteria and the national media spotlight. The mystery deepens when each of the accused girls upholds a vow of silence.

On January 18, 2003, police, alerted by a frantic 911 call from a distraught pair of teenage girls, arrived at the girls Toronto area town house to find their mother dead. It appeared the 44-year-old alcoholic, having slipped into a booze-and-pill stupor, drowned in her own bathwater. The death was ruled accidental by the authorities. In the months that followed, however, police were alerted to rumours and reports that the teenagers had been gossiping to friends about the accident. Police began piecing together rumours that suggested the teens might have had a hand in their mother's death. In fact, rather than an accident, the story that emerged portrayed the two teens as cold-blooded, premeditated killers.
