He volunteers to be an undercover spy working in hopes of preventing raids on the shipments of horses that the Union war effort desperately needs. As he becomes friends with the Confederate raiders, he is able to get secret information as to where they are about to attack next. When the Confederates begin to suspect he might be a spy, he must quickly find a way to squash their fears.
