Nanette Cole and the crew of the USS Callister are stranded in an infinite virtual universe, fighting for survival against 30 million players.
So, the TV series inside a TV series!
I absolutely forgot the previous episode! Which was s04e01 (Season 4, Episode 1), from 2017. Seven years (and a half, almost) between the two.
It’s the first episode of Black Mirror that is the continuation of the previous one!
And the ending is so Inside Out-ish!
The after taste is not pleasant.
