A rag tag team of spelunkers explore an underground desert cave and discover stalactites, stalagmites, interesting rock formations...and flesh eating outer space slime with teeth! Could the poor cave crew be the victims of hostile alien life recently plummeted to Earth? This underseen oddity has a sort of weird overall pacing to it, but is strangely watchable (don't you want to see if Stage Fright director Soavi bites the dust?).

Highlights include a nasty beheading via a toothy slime thing (upside down to boot!), a gooey noggin explosion and various face rippings. None of it is really well done, but who cares? Would make a fun late nite trinity of trash with Cozzi's Contamination (1980) and Warren's Inseminoid (1981).
