Over fifty years later, Dr. Wes Martin, a psychologist, and Elizabeth, a social worker, are working to help seven people who are having the same recurring dream. The dream involves a large Navy ship in a vast desert. There are soldiers trapped inside the bulkheads and slowly, by depriving them of REM sleep, the dream is killing the dreamers.
What the dreamers do not realize is that another vessel -- a modern fleet fit with nuclear warheads -- has recently vanished in a green-grey mist over the North Atlantic. And only Elizabeth, by entering the dream, can prevent its firepower from stopping humanity forever.
