Hell's Headquarters plot
A secret stash of precious ivory lies in a cave deep in the forbidden territory of Congo. It takes a grueling three-week journey on foot through the world's most dangerous jungles to get there. Only two white men know where the treasure is, but one of them, suffering from a fever, dies under mysterious circumstances after entrusting the location to another hunter, Phil Talbot. Desperate to get his hands on the riches, Talbot goes on an expedition with the help of an American entrepreneur and his daughter. When the dead man's original partner arrives in Africa to protect his share of the ivory, the deadly safari becomes even more treacherous.
