S1E1: the opening scene of the first episode is one of sexual harrassment; a man on the tube stands uncomfortably close to a young woman and berates her and others who intervene. He is portrayed unsympathetically and faces law enforcement at the end of the scene. Later, a side character present only in this episode, who is a high-profile politician, is revealed to have gotten away with historical rapes. The rapes themselves are named as having happened, but never described in detail or shown onscreen. Worthy of note: the series plot revolves around the fact that child pornography is on a USB drive. None of the child abuse is ever shown onscreen, only people's horrified reactions when they look at the contents. The paedophile who has put the pornography onto the drive is treated somewhat sympathetically, being referred to repeatedly as a "troubled man" and framed as needing protection (rather than punishment) because of his mental health issues and suicidal ideation. He is never held responsible, but does eventually kill himself. For most of the series, a woman is held prisoner in a cellar by a man. There is no sexual motivation for this and she is never sexually assaulted.
