Like previous runs, season four contains six stand-alone episodes, with each tackling a different genre.
Episode one, Crocodile, is a “beautiful, more personal study”, producer Annabel Jones told The Independent.
“It’s a film set in the near future where your memories are no longer private so they can be dredged – sometimes in helpful ways,” she explained.
Unlike fan-favourite The Entire History of You (season one), the memories in Crocodile can’t be relied on.
Jodie Foster directs episode two, Arkangel, which explores the concept of helicopter parenting.
“It follows a mother who has a young daughter and faces that perennial question of how to look after a child in an increasingly technical world,” Jones said.
Episode three, Hang the DJ, has “quite a lot of sex” and tackles online dating.
It is followed by USS Callister, a “space opera” which promises to be Black Mirror’s most lavish production yet.
“There are obviously more unsettling, poignant and slightly more melancholic moments, but at the same time, it is a romp,” Jones said.
Episode five, Metalhead, is Black Mirror’s first-ever black and white film. Little else is known about the episode.
The season finale, Black Museum, is an anthology within the anthology.
Like White Christmas, it features three separate stories, and is a “a portmanteau-type thing”.
Jones teased: “It’s absolutely full of ideas that whip along and before you know it you’re at the end of a 90-minute film and you’re like, ‘Oh my God, can you please stop? This is horrendous – stop throwing me these things!”
