Based on a true story, "Harley and the Davidsons" will tell the story of how Milwaukee schoolyard pals William (Bill) Harley and Arthur Davidson built - and rode - the machines that rule the road. Beginning at the turn of the 20th century, at the shores of Lake Michigan, the series charts the birth of Harley-Davidson during a time of great social and technological change and tells the epic story of how two 19-year-old kids from Milwaukee started a company in their backyard that would go on to become an American legend.
