Netflix has yet to announce the official release date of "Black Mirror" season 4, but the network continues to drop teasers for the show. After the recently revealed trailer for the series' first episode "Arkangel," a new clip for the third episode, titled "Crocodile," is unveiled.

Compared to the first trailer, the second teaser is set in the near future. Here, an enigmatic organization has the ability to get into other people's memories. "Memories can be subjective," a woman's voice can be heard saying in the background.

After a car accident, a guy reveals that he does not remember anything, and that his memory is a total blank. As the criminal investigation is ongoing, a woman, played by Andrea Riseborough, tries to access his memory to find out what happened and solve the mysterious car crash.

In an interview with Independent last October, executive producer Annabel Jones talked about the "Black Mirror" season 4's upcoming episodes. "'Crocodile' is a beautiful, more personal study," she said.

The third episode has been filmed in Iceland and will be introducing a "totally new palette" to the show. It is set in the near future where someone's memory can be accessed by an organization. Although it can be in a helpful way, this group can search people's memories that removes the public's privacy.

Jones also compared "Black Mirror" season 4's third episode to the first season's third installment, titled "The Entire History of You." "It's very different to 'The Entire History of You' in that they're not accurate -- they're memories rather than recordings," she explained.

Meanwhile, in the first episode's trailer, titled "Arkangel" and directed by Jodie Foster, it features a disturbing setting where a child goes missing. Here, a man can live up to 2000 years and parents are letting their kids to be injected with a kind of a technological device that will make them control their children. "The key to good parenting is control," the teaser reveals.

Netflix has yet to reveal the official release date of "Black Mirror" season 4, but it is expected to be out this 2017.
