It's always high noon in the hollow earth!When a South American hunting expedition for Butch Cassidy and the Sundance Kid goes bad, Doc Holliday, the Earp Brothers, and Native American gunslinger Lone Crow find themselves trapped in the hollow earth along with the vicious killers they were tracking.In order to survive, they make a tenuous pact and throw their lots together against a brutal tribe of female warriors, and the ravenous prehistoric beasts that roam the jungled interior of the planet and soar its hazy crimson skies.With ammunition running low and treachery running high, they follow rumors of a passage to the blue sky of the world without, while a bloodthirsty band of bandidos dog their every step.
