Galen falls through a hole in the ground, discovering a long-forgotten US government germ warfare lab. As a gorilla patrol closes in, Virdon and Burke must follow him in. The gorillas think they have found poison gas to use against the human race but to prevent the highly dangerous germs escaping into the wider world, the fugitives must use dynamite to seal in both the complex and the contaminated gorillas.
