The rise and internal fracturing of the Crowther family wool-trade empire in Yorkshire serves as the catalyst for a multi-generational struggle for control. Simeon Crowther establishes the Bankdam Mills in 1854, but his legacy is immediately threatened by the starkly opposing temperaments of his two sons, Zebediah and Joshua. As the family business expands into a dominant industrial force, the brothers' conflicting ambitions and personal animosities create a volatile environment that risks the total collapse of their enterprise. The narrative tracks the family's evolution through decades of social and economic change, utilizing a sweeping, multi-generational perspective to examine how individual character flaws dictate the fate of a corporate dynasty.

This novel is frequently compared to the works of John Galsworthy for its expansive scope and focus on the internal dynamics of a powerful family. The narrative is noted for its ability to ground large-scale industrial history within the intimate, often contentious relationships of the Crowther clan. Readers often highlight the stark contrast between the brothers as the primary engine of the plot, providing a consistent tension that persists across decades. The work is regarded as a classic example of the regional industrial saga, capturing the specific atmosphere of the Yorkshire wool trade with precision and depth.
