A Latin American country on the Pacific seaboard. A coup d'état fails. Jacques and his fellow mercenaries must get out of there as fast as they can. He takes with him Monica, a beautiful prostitute with a taste for adventure. Having cheated their shady paymasters out of some valuable paintings, their only possible means of escape is by hijacking a bus, fleeing across desert and jungle, and rafting down the river to the Atlantic. Nature is hostile, but much wilder opponents await them!—Anonymous
