Picking up immediately after the events of Farragut Forward, the crew is assigned a critical mission to track down a rogue Starfleet officer who has stolen dangerous radioactive material—powerful enough to be used as a planetary weapon. During their pursuit and attempted apprehension of the suspect, the Farragut is thrust across time and space, landing near Earth in the year 2024. The crew must find a way back to their own era… or risk being stranded in Earth’s past forever.
