Netflix has released the trailer for the Black Mirror Season 4 episode directed by Jodie Foster, and it's called Arkangel. The tagline for the episode is "The Key To Good Parenting is Control" and you can see in the trailer why. After a little girl goes missing in the park, her mother has a major panic attack, but she finds her eventually. However, this causes her to take certain precautions, and it looks like she let a company implant something in her daughter's brain that will probably give her more control over her child, and since this is Black Mirror, we know that it's probably going to make things relatively worse for her.
Watch it here:
The episode stars Rosemarie Dewitt, Brenna Harding (A Place to Call Home), and Owen Teague (Bloodline).
Black Mirror Season 4 is expected to premiere on Netflix sometime in 2018.
