In the darkest days of World War One, four French soldiers (one of them played by a young, pre-Bonanza Pernell Roberts) see a strange light in the sky--whereupon they throw down their weapons and apparently desert their posts. Assigned to defend the soldiers during their court martial, Capt. Emil Tremaine (Bruce Gordon) can neither believe nor sympathize with the defendant's claims that they were motivated to "desert" by circumstances beyond their control. Only on the eve of the soldiers' execution does Tremaine undergo a paranormal experience, proving that there is sometimes a "greater truth" than what meets the eye. (Curiously, "The Vision" is misidentified as the earlier One Step Beyond episode "Emergency Only" by several public-domain DVD merchants).
