SF on a documentary level seeks out a lost speech of Lincoln's in Bloomfield, Ill., in 1856, and Benjamin Steward, of Time Researchers, 722 years later, is sent back to the Old Nation to record it. The snafu of his first survey, which lands him the day after the speech, the run of his second shoot with his crew, the ways in which they fade into their new background, the means by which they try to accomplish their purpose -- and the unexpected ending -- add up to a solid story.
