A couple of fisherman catch something big and heavy on their anchor. Unknowingly they have released Karen Morgan, a succubus who is in love with Nick. She uses another name and disguises herself to 'fall in love' with Nicks friend and then starts to visit Rachel at her Doctor's office. She uses both of them to make sure that she gets introduced to Nick. Meanwhile, to keep herself alive, she is finding violent men on the streets of San Francisco and sucking the life from them.
