The year is 1955, and a great flood is coming to Northfork, Montana. A new hydroelectric dam is about to be installed in the mountains above the town, ready to submerge the valley in the name of progress. It is the responsibility of a six-man Evacuation Committee to relocate the townsfolk to higher ground.
