How would a modern young man react if, on the way home from school, he was grabbed, forced into a car, taken to an unknown place and told that his parents were lost in the distant past? He would probably be scared at the very least. But that’s not the case with Jake Jones, a resident of modern London. He perceives the strange events that happen to him - time travel, meeting amazing people born in different eras, and direct participation in the salvation of humanity - surprisingly calmly and even, moreover, with interest and pleasure... And all only because family The Jonesovs are not ordinary people, but employees of the Secret Service of the Keepers of History, with whom it is better not to enter into confrontation.
