The show features an incest plotline, which is evident from the first episode. It is explicitly revealed in S1E3 that this is the nature of the relationship. The show subsequently includes very graphic scenes of incestuous sex between these characters (brother and sister). A woman is forced to have sex with her husband multiple times. S1E4: a woman is taken into custody and her top is removed as part of an attempt to get her to cooperate. It is then heavily and uncomfortably implied that if she does not cooperate she will be raped. It does not happen.
