Gone on the Road from which There Is No Returning

When the Light Goes Out, the House Is Dark (Pio ke kukui, pō'ele ka hale) is the 10th episode of Season 9 in the remake version of Hawaii Five-0.

Synopsis Edit

After fighting off an assassin in his own home, McGarrett and Joe White flee to Montana to prepare for a battle against those exacting revenge for a past SEAL mission.

Notes Edit

  • The galloping horse movements of Joe and McGarrett in close-up shots don't match the wide-angle shots. They're not really riding the horses. Also, the green-screen background is fairly obvious in those same close-up shots.
  • At the end of this episode Joe White sadly passed away.
