The team travels to what could be a Neolithic settlement in the Sussex Downs. Initially discovered by John Pull in 1923, the site is littered with remains of 6000-year-old flint mines. But Pull claimed to have discovered a second site nearby, which has so far eluded other diggers. The team are joined by archaeologist Miles Russell, pottery expert Sue Hamilton and wood specialist Maisie Taylor. Neolithic lifestyle specialist Jacqui Wood makes some elderflower tea and threatens to make a new hat for Phil. Phil and Francis demonstrate the relative merits of mesolithic and neolithic axes.
