In a flashback, Farquhar and his wife are relaxing at home one evening when a soldier rides up to the gate. Farquhar, a supporter of the Confederacy, learns from him that Union troops have seized the Owl Creek railroad bridge and repaired it. The soldier suggests that Farquhar might be able to burn the bridge down if he can slip past its guards. He then leaves, but doubles back after nightfall to return north the way he came. The soldier is actually a disguised Union scout who has lured Farquhar into a trap as any civilian caught interfering with the railroads will be hanged.
