Armed with metal detectors & trowels, Johnny Vaughan & his mudlarking guide & buddy ' Mud God' Steve Brooker, are on a muddy archaeological adventure, digging up the banks of the Thames to reveal our astonishing hidden history. They only have 5 hours before the tide comes in to wade, search & dig the banks to fin artefacts from medieval chain mail to WW artillery shells & Tudor trading tokens to cursed Bellarmine pots. In each episode mudlark Steve Brooker shows Johnny the tricks of the trade as they set about recovering the important 'rubbish' & lost items of history from the thick black mud that has enveloped them to reveal unique & original perspective on the way our ancestors lived.
