On a military base in Halifax, Nova Scotia, a top secret program assists personnel from around the world when they're experiencing mental health problems. These people can't be helped anywhere else because their jobs are extremely classified: their secrets really are top secret. Dr. Blake Waiter, the program's psychologist, is an ordinary man with an extraordinary job. When a new patient from a research project in the Nevada desert comes to him with a fantastic story and fearing for his life, Dr. Waiter doesn't know what he's about to get involved with. He soon finds himself on a frightening roller coaster of events involving impossible floating balls, an evil entrepreneur, a giant damaged soldier, and a mysterious artificial intelligence.
