From Amazon Prime:

Two girls disappear in identical circumstances in the wilds of Tasmania 15 years apart, and Doctor Anna Macy finds herself linked to both cases. To clear her name, Anna must delve into her troubled past and face some truths about herself and the otherworldly nature of this gothic land.

From Amazon Prime you can stream 8 episodes of season 1. Each episode last about 50 minutes.

Possibly it was the adolescent side of my brain that kept me interested in staying with the series. Each episode added some new mysterious element. At any minute I expected little green men to arrive in a space ship. Alas the green men never arrived and the creepy details just piled up. Still I forged onward hoping for the best.

WARNING:   Do not expect a satisfying conclusion to the story. Instead you get a semi-conclusion that must lead into the next season, which does not seem to exist yet.

Why did I fall for this possible put-on?  Probably because this Australian production is well done with good acting and believable character interaction. In fact, I don’t regret having watched it at all.
