Season 4 will bring Amazon’s alt-history series, The Man In the High Castle, to its grand finale. Based on Philip K. Dick’s original novel, the series explores the potential alternate history of a world where the Axis powers won World War II; in this depiction, the remaining ruins of the U.S. are split between the German and Japanese forces.

The story isn’t as straightforward as it sounds though. While it does entertain a lot of hypothetical ideas, The Man In the High Castle’s unique plot is focused around the concept of a multiverse. The Third Reich, the world dominating force, is very much aware of the multiverse and plans to dominate all other realities. The rebel group in this particular alt-history is salvaging any and all hope left as they prepare to fight to the death. With our hero Crain, it might be possible.

Julia Crain can tap into her unique ability to travel between worlds, placing her in the most pivotal of lead roles. She begins the fourth season in our reality, a safe haven from the German and Japanese forces, and now is more determined than ever to aid the resistance against the Third Reich.

The opposition features John Smith who has presumed authority over the Nazis. He’s the seemingly irredeemable man with plans to invade other realities, but his wife Helen seems to be contemplating the truth. An uncertainty might flare into something greater and steer John off the destructive path, but we have yet to see with this final season.

For Amazon, the jam-packed theoretical action has been an astounding success, capturing the attention of fans since its season 1 premiere in 2015. In that time, considerable changes have been made in positions like show-runner and even additions like cast member Frances Turner.

Telling the story through struggling freedom fighters and the conflict with the authoritarian regime illustrates a narrative of hope with refreshing elements of sci-fi. The final season will take everything from the past and bet everything on the multiverse story line. The journey through time will certainly be a thrilling end, and the Amazon Prime Original will premiere Friday, November 15th as their exclusive.
