This episode starts with Palin crossing the border from Niger to Algeria, a desolate border with nothing but sand. A bit north of here are the Hoggar Mountains. At Assekrem he gets up early to view the sunrise from 9000' (3000 m). Next he boards an Algerian passenger plane and flies north to Hassi-Messaoud, an oil extraction and refining town; a man-made luxury oasis in the middle of the desert. From here the trip jumps to Libya, normally closed to western TV crews. To gain entry Michael Palin and his team have joined up with a British veteran's tour, and he mingles with the 80-year-old former "Desert Rats" who reminisce about the Battle of Tobruk. He also visits Benghazi and the ruins of Apollonia, once a Greek port, and the ruins of Leptis Magna, once a Roman city. Leaving Libya, Palin arrives in Tunisia.
