Chip Campbell, a mesh of man and machine, and an engineer for Cybernetic, Inc. in 3660 A.D., constructs a time machine, dubbed Timetracker. With the help of his super-computer, Roberta, and the oversight of the Time Marshalls, he makes jumps to London, England - Jack the Ripper era, Nazi Germany and several other places to correct errors in the timeline. However, not all is as it seems. Someone else has a control module to Timetracker, and Chip must figure out who it is before the timeline disruptions alter the course of history.
