June 2015, Herefordshire. Two Welsh detectorists - George Powell and Layton Davies - stumble upon a Viking hoard estimated to be worth up to £12m.

They could have become very rich and been celebrated as heroes in museums across the land. But instead, they began to hatch a criminal plot. Narrated by Aimee-Ffion Edwards (Detectorists/Slow Horses), this is the story of how to go from the luckiest treasure hunters on earth, to Newport's most wanted.
