Nine strangers find themselves lost in a remote Mexican jungle after their small plane crashes; the plot thickens as members are murdered one by one and the remaining survivors must solve the mystery.
Nine people survive a plane crash into the Mexican jungle, but they don't know that a murderer lurks in their midst; nine days later, their bodies are recovered by the Mexican army; one of the passengers is missing.
Alliances form, enemies are made and lines are drawn as the passengers search for food and water; when another passenger dies, they realize they may all be targets.
The deadly secret hidden in Flight CBZ517 is discovered, but it still doesn't explain the murders or help the survivors escape; the passengers believe they have found the traitor in the group.
Air authorities search desperately for the plane and federal agencies spring into action; as the group becomes smaller and smaller, the last survivors know they are going to have to fight to stay alive.
