Christina Evans' attempt to get into touch with the mystery of the death of the scout troop, in which her son was a member, immediately turned into mortal danger for Christina and her companion, the former secret agent Stryker. The killers stubbornly followed their trail. At the same time, someone (or something) no less stubbornly conveyed a message to Christina: “He’s not dead! He didn’t die!” Ahead, in the mountains of Nevada, in an underground laboratory where inhuman experiments were carried out and deadly weapons were developed for future wars, Christina and Stryker were expected to meet the Unknown. It was here that they had to get an answer to the question: is mother’s love capable of resisting all the evil of this ruthless world? And is Christina’s son really not dead?
