Detective Annie Cassidy investigates the disappearance of Sarah Polly in a psychological thriller inspired by real cold cases.

ITV’s new crime drama "Gone", premiering March 8, 2026, follows Detective Annie Cassidy (Eve Myles) as she investigates the disappearance of Sarah Polly, wife of headmaster Michael Polly (David Morrissey), in a tense psychological thriller. Inspired by real cold cases like the 1984 murder of Melanie Road, the series explores themes of coercive control and hidden trauma, drawing on the investigative work of former detective Julie Mackay. Though fictional, the show reflects real challenges in solving long-standing cases, featuring atmospheric filming in Bristol and surrounding areas.
