Synopsis

Haunted by the final testimony of a dying whistleblower, Michael Sheen (Good Omens, The Queen) revisits a story that has troubled him for almost a decade. Claims that toxic industrial chemicals were dumped across the communities in Wales where he grew up raise a question he can no longer ignore: are the consequences still being felt today?

Joined by investigative journalists, forensic scientists, lawyers, and local residents, he follows a trail stretching from former dump sites in the UK to the United States, where a landmark legal battle exposed what was known about the dangers of PCB pollution, cause by toxic industrial chemicals once used around the world.

As new testing uncovers signs of contamination decades after the chemicals were banned, the investigation raises questions about corporate responsibility, public health, and whether the consequences of the past are still shaping lives today.
