Most believe she is a myth, that no person could be responsible for the things they claim she has done, that she is merely a bedtime story mothers tell their sons to make sure they grow up to be good.

When a tall, dark woman in a long jacket gets involved for reasons of her own, things really start to spiral out of control...
