Just watched this one ( in German translation)
One could argue if it is AH, but the setting would go well in our ASB section.
The premise is that in 2019 people from 3 different times in the past appear in the modern world.
1. the stone age
2. viking time ~1000 AD
3. the (late) 19th century
Nobody knows why, but they turn up in the water, so some drown on the way.
While the happens worldwide, the series only takes place in Norway, a few years after the first arrival.
The story itself is pretty much a who done it police story with a new policewomen ( herself from viking times) partnering up with an old cops with a drug problem. Classic
But I really like the culture clash stuff.
Check it out. Trigger warning; Unusul male nudity, especially by US standarts. Part of it is in Old Norsk with subtitles.
6 episodes isn't that much, but it got renewed for a second series.
If you happen to be in Germany: the German version is available on the ARD Mediathek.
