Tourists have stolen the sacred codex of the vengeful Mayan sky god. Now airliners are falling out of the sky and it's up to NTSB investigator Jennifer Lynch to figure out why. When the stolen codex keeps showing up at crash sites, Lynch teams with Mayan expert Max Gutierrez and oddball Homeland Security agent Lizard Wong to try to solve the crashes. With both terrorists and the FBI hunting for them, the suspense builds as they try to solve the mystery of how to return the codex and stop the crashes before hundreds more die.
