Realm of the Alligator (1986)

Enter the mysterious, unchartable wilderness of Okefenokee, 700 square miles of swampland on the Georgia-Florida border. Eerie, forbidding, and darkly beautiful - Okefenokee is ruled by a descendant of the dinosaur: the fearsome alligator. Day and night the alligator glides silently through its steamy realm, stony eyes just above the waterline, mouth held in a seemingly perpetual smile. Join scientists as they study the behavior of these huge and powerful reptiles in Realm of the Alligator.
