Amazon Prime Original Series The Man in High Castle Season 3 trailer is now available to watch.

Based on the 1962 novel from legendary sci-fi writer Philip K Dick (Blade Runner, Minority Report), the series imagines an alternate future where the Axis Powers won World War II. Set in an America split up between Japanese and Nazi control, it follows characters whose destinies intertwine after they come into contact with a series of propaganda films that show a very different history from their own.

From the trailer, the upcoming season will delve more into the idea of the series being an alternate reality, with the Nazis developing a mechanical portal to parallel universes. It's up to the small pocket of resistance fighters left to destroy the device.

Watch the trailer below.

The Man in High Castle stars Rufus Sewell, Rupert Evans and Alexa Davalos. The first two seasons are available to stream on Amazon Prime now, while the third season premieres October 5, 2018.

According to Deadline, the show has already been picked up for a fourth season.
