"A geologist battles to save a B.C. town from disaster. He is led through danger and violence to discover the secret of his past."
"A geologist returns to the town in British Columbia where he was the sole survivor of an auto accident, which left him with amnesia and began the rise of another. His return reopens past tensions, leading to a gripping investigation and manhunt."@en
"Bob Boyd has come to Fort Farrell, British Columbia, to carry out a geological survey for the powerful Matterson Corporation, engaged in building a dam. It is a short stay, just long enough for him to get a grubstake together and return to the North-West Territories.

In the ensuing manhunt, his warning that the entire community, as well as the dam, is in danger is ignored - to their peril."@en
