Each episode reveals fascinating insights in the day and night life of some of America's most famed metropolises: Las Vegas, Chicago, Seattle, Miami, San Francisco and Los Angeles. Along with showcasing each city's iconic landmarks and often-surprising history, the series' 4K cameras capture a bird's-eye perspective of the frenzy of work and play that make each city so distinctive - from morning yoga on Miami Beach to the dizzying job of changing a lightbulb at the top of Seattle's Space Needle and the highest open-air cocktail bar in the Western Hemisphere in L.A.'s newest skyscraper.
