Nevada, Arizona and Utah

Alexander travels from the mighty Hoover Dam to the bright lights of Las Vegas and the deserts of Utah, exploring the engineering that reshaped the American west. He uncovers Las Vegas's hidden stories, from homelessness beneath the Strip to the legacy of segregation, and meets craftsmen keeping neon alive, a British magician, and volunteers preparing for life on Mars, before taking on a spectacular rope swing over a vast desert canyon.
