Produced for the bicentennial of the French Revolution, the film's theme is communications. The docu-drama highlights one of the earliest means of long-distance artificial communication: the optical telegraph (semaphore). Invented as a means of transmitting messages from hilltop to hilltop using flagpoles with movable arms, semaphore played an important role in the Revolution.
