Diana Cambridge and Tristan Merrick have set their lives at a change of course, but as the time ticks, Tristan's anxieties are mixed with uncertainty of the future ahead of him. When Charlemagne invites the couple to the manor, they announce the changes in their lives to a troubled Charlemagne who reveals the magnum opus of his innovations: a device he believes can take him into the future. However, the completion of this long-time project is not what troubles Charlemagne as the couple soon find out when their guardian quietly leaves them in order to correct the mistakes of his past, which has resulted in close friends of theirs, or family really, to have wandered into the time machine and become lost in a different world to their own. Diana and Tristan instantly go after Charlemagne, but only for themselves to become lost in a different world where they are forced to confront the issues at hand, which for Tristan, takes the form of confronting his own demons, himself, and then evil itself in order to become the man that he needs to be in order to save Diana, his family, and all those that he loves.
