Unforgotten

All Shows

When the body of a young man is discovered in a derelict building, DCI Cassie Stuart – one of the Met’s smartest detectives – is called in to investigate with her partner, DI Sunil Khan. Jimmy Sullivan was a homeless boy, murdered in 1976 when the building was a hostel. His diary implicates four suspects.

Clergyman Robert Greaves is a devoted husband and father. Sir Phillip Cross, an eminent entrepreneur, is business tsar to the government. Lizzie Wilton is a middle-aged woman who, alongside her husband Ray, works with disadvantaged black kids. And wheelchairbound Eric Slater is carer to his wife Claire, who’s in the early stages of dementia.

Each of them has something to hide. As their lies unravel, the people they love most begin to wonder what else they might be capable of. The more layers of deception that Cassie peels back, the more she realises that nothing in this case is black and white. Can you ever really know the people closest to you? What secrets have they buried?
