Harry gaat met zijn verloofde Ruth op trektocht doorheen het noordwesten. Tijdens de reis lijken er bovennatuurlijke krachten aan het werk in het bos die Ruth in hun macht hebben. Terwijl Ruth zich inbeeldt dat Harry op gruwelijke wijze komt te overlijden, loert paranoia om de hoek en vermoedt het stel dat ze niet alleen zijn.
