About this programme

10/13. Lisa Kelly and GW Boles negotiate a perilous route of narrow tunnels and crumbling cliffs in the Peruvian Andes, while Hugh Rowland transports concrete aggregate along a ramshackle mountain trail to a construction site located 14,000ft above sea level. Elsewhere, Tim Zickuhr and Tino Rodriguez take charge of their first-ever load of livestock, but a serious mechanical problem brings their journey to a grinding halt.
