In 1864, during the Civil War, a band of Confederate prisoners escapes from a Union stockade at Plattsburgh, New York, not far from the Canada–US border. They press north toward Montréal, Quebec, plotting a bold cross-border raid into St. Albans, Vermont to rob its banks in hopes of replenishing the Confederate treasury and to burn several buildings as revenge for Sherman’s March to the Sea. The mission is led by Major Neal Benton, [Van Heflin], a careful strategist who must balance danger with a growing personal doubt about the morality of their actions. The team splits their efforts: some hide out in an abandoned barn, while others move through the town disguised as traveling peddlers, quietly weaving themselves into daily life so no one suspects the coming assault.
In St. Albans, Benton goes undercover as a Canadian businessman and becomes entwined with Katy Bishop, [Anne Bancroft], a war widow, and her warmhearted son, Larry Bishop, [Tommy Rettig], with whom Benton ends up staying. This precarious arrangement gives Benton a fragile humanity to cling to as the raid’s plan tightens. The raiders’ presence remains largely unseen, their intentions masked behind everyday façades, until a drunken member interrupts a church service, forcing Benton to act and shoot the man in order to keep the mission from unraveling. The townspeople, unaware of Benton’s true identity, shower him with gratitude for stopping the disruption, a complicating factor that deepens the moral tension surrounding the operation.
As the appointed day arrives, Benton moves through town as the leader of a Confederate-in-uniform assault, with the other raiders at the barn ready to execute their portion of the plan. Hostages are taken, the bank’s strongbox is looted, and the town hall is set aflame, all while the raiders make their swift ascent northward, pursued by Union forces. They burn a bridge behind them to hinder pursuit and secure a rapid escape route, slipping into Canada just ahead of the tightening net. The exhilaration of a successful getaway sits beside the unease of what Benton has become, and the raid’s outcome lingers as a stark reminder of the perils and costs of war.
