Ten years ago, Hannah's husband was brutally murdered in their home, and she (conveniently) doesn't remember a thing about that night. 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 truecrime 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 history of volatility; citations at the clinic where she worked as a psychiatrist; dependencies on alcohol and pills; and a familicidal grandmother, locked away in a Gothic insane asylum until her death. As Hannah loses the trust of everyone she loves, the only person she feels she can confide in is a former colleague, Darcy, who's come back into her life—but who may have motives of her own. But Hannah can't even tell Darcy her deepest secret: that she's still tormented by the memory of her husband and the crater he carved through her life.
