Every death is unique - and if it is unexplained, unexpected or the cause unknown, the team at the Coroner's Court must investigate it.

With unprecedented access to forensic pathologists, mortuary technicians, police and the Coroner herself, Death Unexplained follows Her Majesty's Coroner Alison Thompson and her team as they examine in painstaking detail mysterious, violent and unnatural deaths in West London, one of the busiest jurisdictions in the country.

Behind each case is also a very human story, movingly told by families themselves and revealing more about the circumstances of loved ones' lives and deaths.

In the first episode, Alison's team investigate a rare case of suspected poisoning; a possible prescription drugs overdose and the case of a man whose body lay undiscovered for months.

In court the Coroner must reach her verdict - who were the deceased and when, where and how did they die?
