From a deathbed tape to a witness in protection, Buried is the award-winning true-crime series digging into some of the most disturbing environmental stories in history.

"It's buried isn't it? But it's coming back." The haunting words of a witness who claimed he'd discovered a toxic chemical secret half a century ago that would affect us all.

In this thrilling new investigation, Buried: The Last Witness, Dan Ashby and Lucy Taylor team up with the film star Michael Sheen, who recorded the witness before he died. Together, they dig into the unseen files of a man who said he was beaten up and put under police protection, after alleging that a chemical had contaminated the food chain.

It is a story straight out of a Hollywood drama: an opera-loving British gentleman clashes with an American corporate giant, claiming there was a conspiracy to silence him. Was the witness right? Science and shadows collide in this true-crime epic, as the hosts search for the truth, testing soil, food and even their own blood - to uncover what one chemical can do at its worst.

Buried is a bingeable, fast-paced true-crime series exposing urgent environmental stories you've almost certainly never heard of. Husband-and-wife investigative duo Dan Ashby and Lucy Taylor delve into thrilling mysteries - bringing to light never-before-heard recordings or boxes of explosive legal documents, inviting the audience to unpick crimes or scandals with them.

Their stories throw them - and us - into secret worlds, be it the organised crime unfolding in our waste, or trails of toxic chemicals that go right to our plates.
