Having escaped capture by the Klingons, a damaged Starfleet reconnaissance probe crashes undetected on the planet Pahl III. Hikaru Sulu, serving as first officer on the retrofitted USS Yorktown, is sent by Admiral Nogura on a secret mission to help locate the missing spy drone. In order to prevent a catastrophic war from igniting with the Klingons, the USS Yorktown (under the command of Captain Bradley Frame) races against time to quickly find the lost drone, with orders to conceal its existence. At the same time, a terrorist group called S.H.A.R.K. discover the drone's location, and plot to steal the device and use it for their own nefarious means.
