The Supernaturals (1986)

Synopsis
The terror in this chiller is more implied and the blood and gore is minimal as it tells of the strange adventure of an African-American female Army Sergeant and her recruits as they head through the forest of Alabama on a survival mission. It all begins when a lieutenant sees the apparition of a mysterious woman. Next a private finds a skull while others are made nervous by bizarre winds and the strangely burned ground thy find. Eventually the unit finds an empty subterranean bunker and that's when people begin to die. Eventually a mysterious fog rolls in and they see that their killers are the ghostly remains of Confederate soldiers who do not realize that the war is over. ~ Sandra Brennan, All Movie Guide
