Some nude and semi nude selfies of a victim.

There is a love making scene between a couple , it implies both of them are completely nude but their body parts perfectly hidden by camera angles. Some light thrusting seen in love-making scene.

Victims are shown/found naked mostly with their breasts exposed but pubic area obscured by camera angles and objects placed on them as a modus operandi of the killer.

There are no sexual scenes included in this entire movie.

Strong sexual innuendo as part of discussion and theme throughout movie; in one particularly strong example, a character speaks of a threesome that he had with his girlfriend and another person.

In the opening scene, a girl's naked body is seen naked, breasts exposed, with debris over her genitals.

There is an autopsy scene where fibres are being extracted which some might find uncomfortable
