You see a girl's butt when Izzy lifts her skirt up. She then rapes the girl with makeshift strap-on out of a severed penis placed on a spike (see violence & gore).

Izzy keeps several teenagers/children hostage in her barn where she tortures and mutilates them.

Izzy attacks a nun and murders a school bus full of people with a gun.

She puts a cage around a child's head with a rat that has been deprived of food, the rat viciously attacks the boy's face.

Izzy castrates a young man and places his severed penis on a spike which she then rapes his girlfriend with. It is not fully shown, but eventually the penis falls to the floor and blood spills as well while Izzy continues to impale the girl.

A young boy shoots himself in the head.

loads of swearing

The torturing and murdering of children/teenagers is fairly intense and disturbing.
