A terminally ill man inherits a remote valley in the Canadian Rockies only to discover it is the target of a massive, corrupt industrial project. Bruce Campbell arrives in the rugged wilderness to claim his grandfather's legacy, but he quickly finds the land threatened by a dam construction project that would submerge the valley. Driven by a desire to vindicate his grandfather's belief in the land's oil potential, Bruce faces physical exhaustion and the machinations of a powerful, unscrupulous contractor. The narrative unfolds through a tense, third-person perspective that emphasizes the unforgiving nature of the mountain environment and the high stakes of the industrial conflict.

Hammond Innes is widely recognized for his ability to blend high-stakes adventure with authentic, rugged settings that feel as much like a character as the people themselves.

The narrative pacing is frequently praised for its steady escalation, moving from a personal quest to a broader confrontation with industrial greed. This work remains a staple of mid-century adventure fiction, valued for its atmospheric intensity and its focus on the intersection of human ambition and the natural world.
