A dead woman is seen impaled by several rebar poles. The wounds are not visible.
We are told a story about an Irish Celtic woman whose children were burned at the stake 100s of years ago. Every Halloween the women returns to steal three children from the living world in exchange for hers being burned alive. If the parent returns within one year of the child being stolen they can have their child back otherwise they are lost forever in the "other realm". This ghost will kill anyone and everything that stands in her path so she can keep the children locked away forever.
There is a surprising lack of violence in this horror film.
One women is possessed and thrown against a wall and is later revealed she burned up from the inside as shown in an autopsy.
A women is thrown from a building to her death (seen from a distance so not very graphic)
One scene with a car accident and it is revealed the driver died instantly. He is shown being wheeled away on a gurney.
