A bridge collapses in a rural community when Spring floods turn the meager Schoharie Creek into a raging torrent, and firefighter Aaron Bonner nearly loses his life among others who aren't as lucky. Worse, he swears he witnessed a vengeful Indian spirit take the bridge down. As he continues to be haunted, Aaron tries to convince the local sheriff that the Native spirit seeks more vengeance. But Sheriff Ben Harrigan has other problems. As Harrigan heads a rescue and recovery operation for victims of the collapse, he witnesses Aaron's growing insanity and worries that Aaron is going down the same path as his Native American father who had a mental breakdown and tried to sabotage the construction of the same bridge 30 years ago.
