The Flame Barrier

Carol Dahlmann (Kathleen Crowley) persuades Dave Hollister (Arthur Franz), against his will, to help her search for her husband who disappeared in the Yucatan jungle while he was searching for a lost satellite. Dave, his brother Matt (Robert Brown), and Carol, after many a harrowing experience, locate the missing satellite and the corpse of her husband (Dan Gachman). Much to their horror, the satellite exudes a mysterious substance which disintegrates anything that gets too near it.
