Three Americans from New York arrive in Oran (Algeria) in 1947. Port Moresby and his wife Kit are accompanied by their friend George Tunner on a trip that will take them deep into the Sahara Desert. Tunner observes, "We're probably the first tourists they've had since the war," to which Kit replies "We're not tourists. We're travelers." While Tunner plans to return home in a few weeks, Port and Kit plan on staying for a year or two.
