A heavily pregnant Erin tries to keep a grip on her sanity as the world around her ceases to make sense. Sean, the father of her unborn baby, is gone. He left amid utterances that he was a werewolf and cursed. Erin dismissed his words as madness but now as her due date approaches, she finds her home under siege. At night, she listens in terror to the sounds of shrill howls that circle her property.
Erin is all alone and something or someone is lurking outside in the darkness. Is she in danger or has she been driven to the brink of madness? What if there was some truth to Sean's curse?
