S1, E2: Dr Alice Roberts' journey takes her from Orkney to Devon, by land, sea and air. In Norfolk, flint tools unearthed push the earliest human occupation back by 200,000 years, to around a million years ago. In Orkney an early farm yields glimpses of our ancestors' earliest religious beliefs and customs. In Devon, we find one of the oldest known shipwrecks.  And a bronze age burial holds a mystery.
