In 1903, Sewall K. Crocker, the youngest mechanic in California, is hired by Dr. H. Nelson Jackson, the man who made a bet to do the impossible, cross America by automobile in 90 days. Along the way they pick up Bud, a goggle-wearing bulldog, who becomes a star in the newspapers. Every mile presents another obstacle to overcome like mountains, rivers, and mud, on the road to New York City. With breakdowns now so severe they have to contact the factory for parts, will Sewall be able to keep the motorcar running before one of the other corporate-backed teams pass them? Sewall understands machines, Dr. Jackson is a dreamer, and Bud is beloved by all, but can this mechanic find the confidence to ensure they all finish this remarkable road trip? The fictionalized account of a true story that changed the way the world viewed the automobile.
