Private Detective John Denson believes in logic. He does not believe in Bigfoot. But when he and Willie Prettybird, his sometime partner who may or may not be a shaman, are hired to help a beautiful Russian scientist, Dr. Sonja Popoleyev, in her search for the legendary sasquatch, a $100,000 reward persuades him to suspend his disbelief. In the Northwest Bigfoot is big business. Their competition: David Addison, land developer, Professor Bonduraunt of the British Museum, Alford and Elford Pollard, local bigfoot hunters, Roger Whitcomb, network personality, and a group of Canadian mountain climbers. Before the expedition can begin, Elford is murdered. With cold hard cash on the line, the searchers are soon scrambling for traces of the elusive creature. But the murderer isn't finished yet, and Denson and his party are on the endangered species list.
