A video game project is driving a developer insane in the first trailer for Netflix's upcoming "Black Mirror" standalone film, "Black Mirror: Bandersnatch."
As Stefan starts to work on the game, he begins to lose touch with reality and has vivid dreams.
"You're not in control," a woman on a television screen says.
"Black Mirror: Bandersnatch" is set to arrive on Netflix on Dec. 28.
"In 1984, a young programmer begins to question reality as he adapts a sprawling fantasy novel into a video game and soon faces a mind-mangling challenge. Welcome back," reads a synopsis.
The special is not a part of "Black Mirror" Season 5 which is expected to arrive on the streaming service in 2019.
