Abe, a kindly neighbor of Lucas', has suffered a mental shock during the Civil War, and as a result believes he is President Abraham Lincoln. Because he is harmless and well-liked, the people of North Fork good-naturedly go along with his impersonation; however, Abe innocently gets into trouble when a brutish stranger derides his innocent masquerade and calls him "crazy." Lucas tries to help Abe, but finds himself and Mark subjects of the stranger's hostility.
