Contains strong sex and sex references. Most of the sex & nudity is suggested through various conversation and settings rather than actual depiction of it.

Some episodes contain scenes of sex, some strong, sexual threat and sex references including discussion of topics including sexual sadism, rape, fetish sex, sexual violence, obsession, and child sexual abuse. Notable scenes include a couple having sex on a bed (with some brief female nudity), a man thrusting on top of a woman who he has kidnapped whilst another man watches (it is suggested both are naked), a teenage boy receiving oral sex from another young man, a young man masterbates while watching a woman in a shower (he is shot from the waist up) and photographs used within an interrogation that depict sex acts. A strong scene of sexual violence depicts a group of men raping a young woman while they force her partner to watch; the scene is brief but it shows men holding her down whilst one kneels behind her and thrusts into her, with focus on their facial expressions rather than explicit detail. There is also a scene where a cellar is shown to contain numerous tools, including sex toys and other such implements, that have apparently been used on children.

Contains strong violence and gore

Episodes frequently contain scenes of violence, some sexual, including references to murder scenes. There is also a large amount of crime scene detail and forensic gore. Notable scenes include a storyline involving a killer who penetrates their victim's skulls using large nails.

In a very gory scene of drug-fuelled hallucination, a character imagines tearing into the flesh and pulling out the internal organs of a young woman.
