In September 1964, Captain McLeod and Sergeant Barnes were dispatched from Wright-Patterson Air Force base in Ohio. They were sent to investigate a UFO sighting in Northern California.

Wright-Patterson AFB got lots of UFO reports. 99% of them could be explained. And a sizeable percentage of those sightings were hoaxers looking for attention.

The other 1% were classified as UFOs and sent on to Project Blue Book. What happened from there, McLeod didn't know. The fact that he was being sent to the other side of the country meant this sighting was important to the Air Force.

McLeod had a copy of the teletyped report from the UFO tracking office. It was stamped with an unusual "Priority" notification. It read: 

"UFO landing with entities reported by missile technician in Tahoe NF, Sacramento. Orders: Investigate and contain via usual protocols ASAP."

McLeod's first step was to interview the witness. And, even after 17 years as an investigator, this was strangest UFO story he'd ever heard.
