After the brutal murder of one of their own, the covert religious organisation known as the Order of the Black Habits recruits Sister Kelly. As Sister Kelly begins her training, honing her skills in martial arts with the help of her extraordinary teachers, a new avenger emerges: the unstoppable, hard-as-nails Sister Wrath. Now, bent on making those who killed the nun pay in blood, Sister Wrath will stop at nothing to uproot evil and the ruthless leader of the local mob, Momma Rizzo. Will Sister Wrath fulfil her divine mission, or will she meet her Maker sooner than she thinks?
