A teenager is imprisoned by a man claiming to protect her from a vicious beast in this dark thriller set in the Welsh countryside. Deep in the wilderness dwells a creature that hunts not for survival, but for the thrill of the chase. Sophie is a girl who lives to explore the unexplained. She’s heard the stories about the mysterious animal, and can't resist the opportunity to find out for herself if it really exists. Venturing out into the fields with her friends, Sophie becomes the victim of a savage attack, and awakens in a locked room. On the other side of the door is Gavin, a man who wages an unrelenting struggle to hold the beast at bay. Is he keeping Sophie locked up for her own protection, or are his motivations more malevolent than he's leading on? Sophie's only hope is that her friends will come looking for her, but even if they do, that's no assurance that anyone will make it through this horrifying ordeal alive.
