A young woman named Anna, desperate to escape her abusive husband, flees into the deepest part of the forest. Injured and terrified, she is protected by an otherworldly-seeming wolf. When dawn comes she discovers the reason; the wolf is a man named Isaac. Isaac was born under a curse, and to avoid harming human in his wolf-form, he lives in the deepest and darkest part of the wood. Can Isaac protect Anna, or will fate force him to make an impossible choice?
