Beauty may be skin deep, but sometimes staying young and beautiful is pure hell.

They say there's no rest for the wicked, but Garen and Luke are eagerly anticipating a brief vacation on the South Island, doing nothing more taxing than tramping, skiing and snowboarding.

However, when Garen meets up with an old friend—a ranger in the nearby national park—he not only finds that several trampers have gone missing there but also that his friend has a new boyfriend, Harper.

Although on vacation, they visit the one tramper who was found alive. Luke detects an aura of evil that is still preying on the man. While he performs a ritual cleansing to free the man of the demonic power's lingering touch, Garen goes into the forest.

When he's attacked by an unseen entity, Garen manages to escape. He returns with Luke to locate a body so that they can identify what is lurking in the forest's depths.

Although Garen suspects that his friend's new boyfriend is possessed by the demon they seek, Luke is less convinced. When the Dearg Due strikes, she aims for Garen's heart, and Luke and Garen must battle to defeat the undying Red Thirst.
