It's Christmas in Australia as Diane, played by the Dee Wallace, brings together her estranged family for a chaotic holiday gathering. A 20 year old decision literally comes back to haunt her when the ghost of Christmas past comes knocking at her door and is invited inside the family estate. Festivities quickly turn blood red, when the stranger is revealed to be Cletus, Diane's aborted fetus, all grown up, very much alive and ready to terrorize his long lost mother. Diane must face her past and explain the hideous truth that is trying to kill them all, especially to Jerry, her Down Syndrome son, before it's too late.
