 Carol Dahlman (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 sattelite. 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.
