Age is just a number when killing monsters is your specialty.

When Markie is attacked by a vampire, she finds out that her lovable grandma is more than she appears. A retired vampire hunter, G is forced to get the old gang back together when the very monsters that the ladies thought they had hunted to extinction show up in their town again.

Between knitting needles and fanny packs, psoriasis and holy water, Markie will soon realize that age really is just a number and that a handful of cranky old women can be scarier than any vampire bite.
