The film contains a prolonged sexual scene between the male protagonist and two women behind a frosted panel in the bathroom before they move to the bed. Both women are naked, bare breasts are actually visible for less than ten seconds total over a duration of 2.5 minutes. There is an implied scene of fellatio when the two women's heads are seen positioned at the male protagonist's crotch. There are also brief close shots of the silhouettes of the women's bodies pressed against the frosted glass, where shots of the women's bare breasts can be seen as well.

While this scene is fairly prolonged and is accompanied by some nudity, much of the action is implied rather than depicted explicitly.

In addition, the film contains another fairly strong sexual scene where one of the women tries to arouse the male protagonist against the latter's will, by straddling him as he is tied to the bed.

The film also features some nudity as seen in a scene where the two women press their bare breasts and bare buttocks against a glass door in an attempt to distract the male protagonist, and some crude illustrations of the male genitalia as seen on various sculptures as the two women try to vandalize them.

There are several prolonged dialogues about and mentions of sex throughout the film.

Some of the stronger scenes of violence in the film include one where a woman stabs the male protagonist in the shoulder with a fork, as well as a scene where the two women tie up the male protagonist and interrogate him.

The film also features strong coarse language, such as the expletives 'f**k', 'motherf**ker' and 'c*nt' as uttered by the main characters, usually in an aggressive manner.

A man is about to light a pipe, which is implied to be filled with weed, but he is interrupted.

A woman tells her husband not to smoke weed.

A man throws away a cigarette.

One of the female characters smokes cigarettes on several occasions throughout the film.

"Dark comedy."

'Knock Knock' is a thriller about a married man who becomes a captive in his own home when he lets two nubile female strangers into his house on a rainy evening when his family is away.

Rated R for disturbing violent behavior, strong sexual content, nudity and language
