Assistant psychology professor Calvin Aguila is on his way to work in the Northern California coastal city of Eureka when he comes across a naked woman lying in a ditch.

Thinking she was a victim of sexual assault, she claims to have no memory of how she got there. Touching her, he feels a spark that sets off his inner alarms.

Returning the woman to her apartment, Cal recalls that his first glance at a distance showed something other than a woman: a deer … or something else?

While eating dinner wth the woman he now knows as Bella Donna Hirschjager, FBI agent, Cal sees a man drug a coed's drink. Preventing her from getting kidnapped propels the academic into a fight between the fed and human traffickers on the surface ... and three werewolves.
