Russ and Everett have been separated from the main Hollow Earth Force. As they struggle to survive in the depths of our planet, they are assailed by strange Insectoids who can drop from hidden passages in the ceiling and pass through walls like they were butter.
They just can't seem to get any relief when they fight a decisive battle with a new group of Insectoids they choose to spare the life of a wounded one. They nurture it back to health and it becomes their friend.
Rowwf as it is named brings them to a hidden city deep beneath the earth where there are thousands of Insectoids appearing to live in peace.
But nothing is ever what it seems and soon the two men are battling once more for their lives with no apparent hope of ever rejoining their comrades.
