A group of FBI agents is sent to investigate a strange crime - the apparent hijacking of a cargo plane in mid-flight. The flight resulted in a mid-air collision with another plane. The flight recorder showed that someone other than the pilots was in the plane. The plane crashed in the wilderness of North Dakota, during winter. Something far darker than agents can imagine is behind the crash. The answers lie in the desolate plains. (Part two will be posted next - this was a bit too long to post as a single AP).
