Colonel Tobin's private army is on the march... against enemies plotting to overthrow a South American government! BRAZIL ERUPTS... A country that finds itself caught up in the throes of a bloody revolution. The regular army cannot cope with the well-armed outlaws, guerrillas, and native tribes with poisoned arrows of this fanatical force.

And so the word goes out: "Get Colonel Tobin!" - and his hand-picked, hand-trained collection of the hardest, strongest, most efficient mercenary fighters in the world. Men who live, work, fight, drink, and love like the devil himself; an odd band of angels who fight for their own reasons...and together are the best damn bunch since the dirty dozen!

The only men on Earth who can stop a revolution...or start one, if necessary.
