As the USS Themis meets with official delegates from the Krenim Imperium, a radical faction seizes an experimental temporal ship, intending to erase their mortal enemies, the Rilnar, from existence. Amidst the chaos, the Themis is sent hurtling back in time, almost one hundred years. Furthermore, they are no longer in the Delta Quadrant but in close orbit of Bajor. Stranded in the past with her ship damaged and her people in danger, Captain Cambil faces a heart-wrenching dilemma: should she uphold the Temporal Prime Directive at all costs? As the Themis crew races to track down the radicals and their powerful vessel on Bajor, Cambil must navigate the murky waters of temporal ethics and personal sacrifice. Will they restore the timeline and return to their own era, or will their actions ripple through history with unforeseen, potentially catastrophic consequences?
