As the world awaits the return of a crew of astronauts from a deep space mission, a young woman named Thelma Joyce appears on a television talk show to discuss caves.
After the spacecraft returns to Earth missing its occupants, a girl on a beach discovers a weird, blue, pulsating rock.
The group arrives at the cave, and quickly rappels to the bottom to set up camp for the night.
The next day, Thelma's friend Jill discovers the blue rock that Burt found appears to be pulsating.
While the group prepares to climb out of the hole, a creature erupts from Jill's face and attacks Ron's neck.
Ron is dragged upside down as the creature slices his neck repeatedly until his head falls off.
Maurine stumbles upon what seems like a living wall, which drags her into it and subsequently kills her and Burt who tries to save her.
