Unlike previous trailers we've seen for Black Mirror, this one focuses in on a single episode that's directed by Jodie Foster.

From what we're gathering from this short, one-minute trailer for the episode - called Arkangel - is that it's going to involve something to do with needles, over-protective parents, creepy children and some deeply disturbing and incisive views on technology and the human condition.

Take a look.

As well as a trailer, Netflix also debuted an in-world promotional poster for whatever Arkangel is. There's still no word on a release date for Black Mirror's fourth season, or where Arkangel is in the order of it all, but nevertheless, we're excited.

Here's the poster.
