There's a big drought in Africa. Food and water are scarce. 90,000 wild baboons suddenly start attacking humans and eating them in order to survive. Some people find themselves being hunted by the starving monkeys and must do whatever they can to stay alive.
The US military is running a test for a special type of radio transmitter, to be used to communicate with submarines, in a deep system of underground caves in Central America. When the signal from one of the transmitters suddenly disappears, a team of soldiers led by Major Elbert Stevens (Bottoms) and cave specialists led by Rupert 'Wolf' Wolfsen (Powell) including scientist Leslie Peterson (Blount) are sent in to find out what happened. Exploring deep underground, they stumble upon a tribe of albino cave-dwellers who have apparently been isolated from the rest of the world for thousands of years. The cave-dwellers are hurt by radio frequencies and are able to see in infra-red frequencies, tracking the explorers by their body heat.
