Thirty years ago a major Thruway bridge was built across a small creek near the town of Fort Hunter, New York. It had its problems with construction delays and local protests, but it was built and it was strong.
Thirty years later the bridge collapses when spring floods transform the meager creek into a raging torrent. The collapse takes several lives and almost includes the life of Aaron Bonner, volunteer firefighter, who swears he saw a vengeful Indian spirit take the bridge down. He just needs to convince Sheriff Ben Harrigan that the same Indian spirit seeks more vengeance. But the sheriff knows that Aaron is just like his father, who tried to sabotage the bridge when it was first built, while in the throes of a mental breakdown. Has Aaron gone crazy? Or does the sheriff have something to hide?
