Feels cut short.....but there's a related documentary that's interesting
Felt like it was a ten episode show that was cancelled after 6, the ending made no sense.
That said, looks like the Bachmann charachter was based on Otto Skorzeny, an ex Nazi that fled to Spain and became a power broker of sorts. There's an interesting Spanish documentary about him on Netflix as well. Explains why Bachmann wasn't worried about himself getting captured, or how he blatantly showed off his Nazi past.
