Molly Cervantez and Sergeant Eutimio (Stephen) Chiac are once again hurled into the dangerous and mysterious world of Sisimito (Mahanamatz), the Cockscomb Basin, and the Maya Mountains, Belize. As Eutimio tries to rescue Molly from the dreaded Sisimito, he enters the darkness and evil wonder of the Maya Underworld and has to use the wit and cunning of the Hero Twins, the gods Hunahpu and Xbalanque, if he is to escape the City of Xibalba and the Death Gods, and continue his mission to save his future wife, Molly. He has to survive many trials including those of the six houses of the Cavern of Trials: Dark House, Rattling or Cold House, the House of Bats, Jaguar House, Razor House, and Hot House. Then he must escape Xibalba through the dreaded River of Scorpions in order to return to the Surface world, U Wach Ulew.
