The narrative opens at a national convention where a young, ambitious political organizer named Al Barslow seeks a moment of quiet, only to become an unwitting witness to the passionate courtship of a country girl and a dark, intense stranger in an art gallery. Returning to his home state, Barslow soon drifts away from his political career and joins his boyhood friend, Jimmie Elkins, in the booming town of Lattimore. Elkins operates as a master promoter of speculative ventures, transforming the quiet frontier town into a roaring center of commerce, real estate, and railway ambition.
As the town expands rapidly through the combined efforts of local speculators and eastern capital, Barslow finds himself drawn deeper into the web of corporate expansion and financial syndicates. Elkins orchestrates the creation of trust companies and railway connections to challenge existing monopolies, driving the local populace into a frenzy of buying and selling. Meanwhile, the dark stranger from the art gallery reappears in Lattimore under the alias J. Bedford Cornish, posing as a wealthy financier while quietly pursuing his old acquaintance, Josephine Trescott, whose father has grown unexpectedly rich from the skyrocketing value of his farm.
The narrative follows the intricate social maneuvers of Lattimore's rising elite, marked by elaborate gatherings, elaborate celebrations of civic progress, and the romantic pursuits of the town's prominent figures. Beneath the surface of prosperity, however, the financial structure grows increasingly precarious, fueled entirely by credit, speculation, and ungrounded expectations of endless growth. At the same time, personal tragedies strike close to home as Josephine's father struggles unsuccessfully against the temptations of the new urban environment, culminating in a sudden and devastating loss that shatters the family's peace.
As the boom reaches its dizzying peak, the characters must confront the reality of their artificially created prosperity and the fragility of their financial empires. The tension between the glittering surface of corporate success and the underlying human cost builds steadily, leaving the protagonists to navigate the consequences of their unbridled ambition. The story closes on a note of impending reckoning, suggesting that the feverish energy of the boom years must inevitably give way to a sobering reality.
