Watch HDToday. Filmmakers Nicolaus Humbert and Werner Penzel examine the nature of nomadic existence in this documentary, from the literal nomads of North Africa to the more metaphorical kind of wanderer, such as American poet and ex-pat Robert Lax. Humbert and Penzel focus especially on the nomad's paradoxical ability to fully inhabit every moment while remaining coolly detached from specific locales and anxious thoughts about the past or future.
