Episode 1
Haunted by a dying man’s warning, Michael Sheen explores claims that chemicals have contaminated land in Wales and England. He follows a toxic trail to ask: who’s in danger now?
For years, Welsh actor Michael Sheen has been haunted by a story he discovered online about little-known farming consultant Douglas Gowan, who claimed the people of Wales had been poisoned by decades of toxic chemical dumping of polychlorinated biphenyls (PCBs) - a known class 1 carcinogen often called the 'godfather of forever chemicals'.
Unable to let the story go, Michael follows a toxic trail that leads him to ask: who’s in danger now?
