It is implied that David De Santis and a prostitute have sex in David's bedroom.

David is seen completely naked a few times. His penis is clearly visible.

David rapes a woman a few times. The woman then stays completely nude for the rest of her appearance, with sometimes visible breasts and public hair.

A boy and a woman yell several times.

Any sensitive viewer might find the violence taking place later in this "found footage movie" to be disturbing/intense, as these scenes tend to look realistic sometimes.
