Major Bennett Marco, Sergeant Raymond Shaw, and the rest of their infantry platoon are kidnapped during the Korean War in 1952. They are taken to Manchuria, and are brainwashed to believe that Shaw saved their lives in combat — for which Congress awards him the Medal of Honor.

Years after the war, Marco, now back in the United States working as an intelligence officer, begins suffering the recurring nightmare of Shaw murdering two of his comrades, all while clinically observed by Chinese and Soviet intelligence officials. When Marco learns that another soldier from the platoon also has been suffering the same nightmare, he sets to uncovering the mystery and its meaning.
