The 4th season of the Black Mirror series started in Netflix on December 29th 2017 with the episode USS Callister.
The plot evolves around a psychopathic coder (Daly, played by Jesse Plemons) in a software company creating a virtual reality game where customers can in a dreamlike state witness the events happening. The coder makes digital copies of the real workmates by using their DNA and then traps them inside the game.
They are forced to play along to pleasure the coder, who is the captain of the ship in the game. They cannot defeat the captain in any way. And if they refuse to play along they are tortured, like suffocated for a while. Another time the (copy of the) young son of one is thrown out of an airlock. The copies also cannot die. Even if they committed suicide, the coder could recreate them because he keeps their DNA in the real world. Being a 60s Star Trek (TOS) like game set in the 60s one of the characters claims there is no sex. Also showing where his genitals should be, there is nothing. They have no feelings, cannot even take a dump. Their only pleasure is a bar filled with alcohol.
When a new copy (Cole) comes into the game she decides to fight back. But first has to convince the others to do so.
The cast played their roles well, the story was compelling. In my opinion one of the best episodes since San Junipero and Node dive. Really enjoyed it and look forward for more episodes.
