In an alternate 1899, farm boy Solomon Hunt leaves home after his father's death to seek income for his family, only to stumble into the adventure of a lifetime when he rescues a young genius showman from captivity in a sideshow. Together, the duo flee across the terrifying, entertainment-obsessed Empire of America, performing for a living while evading a group of vicious pursuers led by Leonard J. Coop, who not only dominates the Empire through his circus-like extravaganzas, but seeks to be president too. From Buffalo to New Orleans, Denver to Los Angeles, and everywhere in between, Solomon befriends and recruits diverse young performers trapped in shows, including a human cannonball, a giant acrobat, a blues musician, an outlaw gunslinger, a talking gorilla, and more. As Coop closes in and vile secrets are revealed, the ragtag troupe reaches little Hollywood, California, where they present an explosive, groundbreaking performance intended to save them all.
