In the 1850s, communications between the east and the west of the country were one of the great challenges of the United States. Abraham Lincoln's government, concerned about the beginning of the Civil War, decided to finance the junction of the telegraph between Carson City (Nevada) and Omaha (Nebraska). It was the end of the Pony Express and Lucky Luke joined the team connecting Carson City to Salt Lake City. Another team had to connect Omaha to Salt Lake City. The Western Union offered a $100,000 bonus to the first team arriving in Salt Lake City, which would attract the lusts and all sorts of boredom to Lucky Luke.
