好奇心强又活破好动的乔吉雅，一直说服男友麦特前往英国乡间寻找传说中怪兽伊克斯莫尔的踪迹，用亲自拍摄的影像，向世人证实他的存在。途中他们碰到拥有20几年打猎经验的猎人福克斯，他认为怪物曾经吃过人肉，担心两人的安危，所以愿意当两人的嚮导，共同揭发事实。于是在进入令人窒息的茂密森林之后，凝重的空气与恐怖的气氛将他们团团围绕，而福克斯居然逆转成为猎人的囊中猎物

With their sights set on a £25,000 reward promoted by a local newspaper, American documentarians Georgia and Matt head to Exmoor in North Devon to film the fabled beast supposedly slinking through the remote terrain. Is the creature a leopard, a panther, a family pet crossbreed, an imaginary predator? Setting up a forest camp with an old acquaintance harbouring his own dark secrets, the trio fix 42 cameras to the trees and rocks, linked back to a computer nerve centre where nothing should go unnoticed as they take turns to night watch. But then they discover some putrefying body parts all neatly tied up… then some more. And before long they realise they are in the lair of a beast right enough, but certainly not one of the four-legged variety. For they have discovered a serial killer’s playground and are soon to become his most wanted prey.

Georgia och Matt reser till det avlägsna Exmoor i norra Devon för att hitta och fotografera de legendariska pantrar som sägs leva på heden. Tillsammans med Fox, en spårare som fått nys om var odjuren håller till, ger de sig in i den oinbjudande terrängen och upptäcker till deras fasa döda människokroppar som inte verkar ha fallit offer för några djurattacker. Snart inser de att de inte är ensamma på heden, och att Fox haft andra planer för dem än han berättat om.

İki Amerikalı, Exmoor’un kırlarında gezen vahşi kediler hakkındaki söylentileri duyunca İngiltere’ye doğru yola çıkarlar. Kırsala vardıklarında bir avcı ile tanışırlar ve vahşi hayvanlardan birini bulmak üzere harekete geçerler. Ancak bulacakları şey, umduklarından çok daha farklı olacaktır.
