Cmdr. Rabb and Lt. Austin travel to Okinawa to investigate the murder of a Navy sailor. After finding nothing to go on, the two join the sailor’s ship, which is about to test an experimental ship and weapons control software system. However, during the test things go horribly wrong and it becomes clear the software has been sabotaged, leaving the ship adrift and vulnerable to the impending arrival of several North Korean naval vessels. To make matters worse, the ship’s weapons are now set to track and fire on any U.S. rescue response.
