Paleontologist Grant Coleman and environmentalist Janaina Silva, lost in the Amazon rain forest, discover an isolated logging camp, and the chance to hitch a ride back to civilization. But the workers uncover a fossil of a giant snake, almost fifteen meters long. Grant is thrilled, but the superstitious workers believe they have let loose a demon. That night, the world begins to unravel. A mysterious creature attacks the camp, kills several men, and sinks the only boat that can get them home. Soon Grant and the others are in a battle against colossal spiders and a descendant of that great fossilized snake. The key to survival might lie in the lost pyramid of the Aztec Viper King, hidden deep in the rain forest. But they need to get there alive, and one member of the crew has an agenda that doesn’t include Grant and Janaina ever getting home.
