Location of events unknown.

Various shots show a man having his fingerprints taken when he arrives at a prison. A man studies the prints with an eyeglass then compares them with some others from a file, using the fingerprints to trace the prisoner's past. As there is already a set of his fingerprints on the file, a man adds the details of the criminal's previous conviction to his current index card.
