An investigation into the last pitched battle to have taken place on British soil, the Battle of Culloden in 1746, on the outskirts of Inverness. Rick Edwards and river detectorist Beau Ouimette search for clues as to where Bonnie Prince Charlie, crossed the River Nairn as he fled the battlefield pursued by government forces. The battle was to have an impact for decades to follow on those on the losing side, the Jacobites who wanted to restore the Stuart lineage to the British throne. The Jacobite forces were shot down as they carried out their famous Highland Charge across the moorland, and some of those who survived escaped and crossed the River Nairn in an attempt to return to the relative safety of their homelands.

Rick Edwards and Beau Ouimette look for evidence of Roman life in Scotland, heading to Ardoch Fort in Perthshire, on the east bank of the River Knaik. It spans over eight and a half acres and was built under Agricola around 80AD on the east bank of the River Knaik. The fort occupied a key strategic route through Perthshire and into north-east Scotland from the First to Third centuries.
