History is written by the winners – but in the ground beneath our feet, lie secrets someone has tried to bury. We travel back in time to 878AD, a world of warring Anglo Saxon kingdoms and Viking invasions. Historian Gareth Williams reveals how the coins found by George and Layton could rewrite the story of King Alfred’s reign and of Britain itself.

Trying to throw authorities off their scent, George and Layton hand in precious pieces of gold jewelry to a museum in Cardiff, spinning a story about how and where they were found. But archaeologist Peter Reavill isn't convinced - and as the true scale and value of the hoard become impossible to ignore, so do George and Layton's lies.

In the close-knit detectorist community, secrets don't stay secret for long. With rare Anglo-Saxon coins in their possession, George and Layton turn to coin dealer Simon Wicks. But as coins start appearing at a Mayfair auction house, whispers of an undeclared hoard begin to spread.

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.
