Benjamin Jensen's best friend in all of time, Brad Jorgen, returns from a long-term research project with important news. Someone is traveling in time disrupting the time stream. Benjamin and Brad are tasked to repair, and insure it does not happen again. Afterwards, the Archive Academy requests that the two of them teach a course in how to be inconspicuous when performing research, and how to improvise when things do not go as planned. The class is a hit, but there are a lot of bumps during the learning process. Including a covert trip to Pluto to reclaim a ship they left on the once and former planet several thousands of years earlier, one they will need to use to revive a civilization which has been dead and forgotten to the passage of time for several millennia.
