The mom for no reason that we can understand tells Nathan that the family dog they euthanized has gone to hell. Arguably the whole plot of the movie could've been avoided if she hadn't been an ass.
There is a depiction of the brazen bull torture, where someone is locked inside a steel structure (in this case a Baphomet statue) with a fire heating up the metal. Someone dies from this, while another character gets saved from this fate in the nick of time. Two characters are also locked inside a cage.
A man kidnaps a girl and her younger brother and taunts the girl and takes her jacket off of her while she is in a small cage. She appears to be a teen.
Nathan has scratches on him he says demons put there, they are not gory but a little bloody. There is also a really bloody dog’s bite, but you can easily avoid seeing it when the dog goes in to bite him look away until the tin can tink.
They find a gun early on, and it is unsuccessfully used twice. The hunters that kidnap them have guns and appear to shoot them, but it is implied they are tranquilizer guns. She shoots and kills both the hunters later. There is a gun in the snuff film sections that flash in.
Two people are placed in a brass bull like torture device, after being kidnapped. There are shots included from (fake) snuff films that include and imply torture.
