Ten years ago, Hannah’s husband was brutally murdered in their home, and she (conveniently) doesn’t remember a thing about that night. But the police charged someone else --- a stranger --- and put him away for life. And Hannah packed up her six-year-old daughter and left London behind. But now her hard-won countryside peace is threatened. “Conviction,” a viral true crime podcast known for getting cases reopened and old verdicts overturned, has turned its attention to Hannah’s husband’s murder for its new season. They say police framed the man who was found guilty, and that Hannah has more suspicious secrets than just her memory loss.

A new student, Violet, steps on the campus of Elm Hollow Academy, an all-girl’s boarding school on the outskirts of a sleepy coastal town. This is her fresh start, her chance to begin again in the wake of tragedy. She is soon invited to an advanced study group, led by her alluring and mysterious art teacher, Annabel. There, with three other girls, the five of them delve into the school’s long-buried grim history. Violet quickly finds herself wrapped up in this heady new world of lawless power --- except she is needled by the disappearance of a former member of the group, one with whom she shares an uncanny resemblance. As her friends’ actions take a turn for the darker and spiral out of control, she begins to wonder who she can trust, all the while becoming more deeply entangled.
