From the earth to the moon: It's been some time since the end of the American Civil War. The Gun Club, a society based in Baltimore and dedicated to the design of weapons of all kinds (especially cannons), meets when Impey Barbicane, its president, calls them to support his idea: according to his calculations, a cannon can shoot a projectile so that it reaches the moon. After receiving the whole support of his companions, a few of them meet to decide the place from where the projectile will be shot, the dimensions and makings of both the cannon and the projectile, and which kind of powder are they to use.
