Are you considered a good parent if you insist on injecting something into your daughter’s skull after you temporarily lose her at a playground? And then that injection starts to make your daughter do weird things, like make dogs go into a barking tizzy and broodingly stare off into the distance? Black Mirror season four presents this very specific predicament for your viewing pleasure! The trailer for the season’s Jodie Foster–directed episode, “Arkangel,” has premiered, which features Rosemarie DeWitt’s character at a crossroads with her child. Whether or not that injection will actually help will be revealed in 2018, when Netflix releases the full season.
