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.
