Doug and Tony are transported to Gettysburg in the American Civil War. Tony is killed in an explosion, but the time tunnel personnel revive him with the shock of a power surge. Meanwhile Doug is saved by a Union major and wears the Yankee uniform. When the confederate Sergeant Maddox meets amnesic Tony, he believes he is a courier and he wears the confederate uniform. When Doug and Tony meet Machiavelli, who had accidentally been brought by the time tunnel, the man tries to manipulate the time travelers.
