Brace yourself, because Black Mirror is coming back. The deeply unsettling sci-fi series has released four trailers for its upcoming season, the latest of which does something we didn't think possible: it makes online dating look even more awful than it is IRL. Another of the season four teasers features a paranoid single mother agreeing to a disastrous medical experiment on her young daughter. We don't glean too much information about that episode from its quick clip, but viewers do receive a haunting piece of child-rearing advice: "The key to good parenting is control." Looks like we're in for a spooky season, y'all!

The first trailer was released in August, and it will not only give you minor heart palpitations, but also reveals the names of each of the season's episodes and a glimpse at the new cast. The six episodes in season four — "Crocodile," "Arkangel," "Hang the DJ," "USS Callister," "Metalhead," and "Black Museum" — will feature appearances by Rosemarie DeWitt, Daniel Westwood, Gina Bramhill, and Jesse Plemons. The series is written and executive produced once again by the show's creator, Charlie Brooker, and Jodie Foster is listed as the director of the "Arkangel" episode (which stars DeWitt and appears to involve some kind of evil child situation). The official premiere date is Dec. 29, so for now, enjoy the new, latest trailer above and catch up on the other three bone-chilling sneak peeks below!
