Nick, Wu and Hank must link strange cases of people frozen to death and suspect they all had contact with a type of feral which dies from frost unless it can drain body heath. The link between suspects is biological: Sven, Knut and Jalmer are brothers. Following them leads to what Monroe expected: a lair for hibernation, but disturbing them to attempt arresting the killer proves dangerous. Raging for revenge, Juliette attempts to murder Adalind, but prince Kenneth's henchman proves a worthy bodyguard.

Opens with the quote, "Ah! It was colder than ice; it penetrated to his very heart." This is from the fairy tale The Snow Queen by Hans Christian Andersen.
The location of the second attack is "route 4, marker 17". This is probably part of the episode-number running gag of the show, incorporating the episode numbers in the actual episodes, being episode 17 in season 4.
The first victim on this episode lived in the farm house at 16636 S. Hattan Rd Oregon City, OR.
"Hibernaculum" is the Latin nominative (and vocative) case noun for 'winter residence', or 'place of hibernation'.
Esther Blake is frozen solid; Nick says the bite on her trapezius looks like frostbite. Given that frostbite is when skin and underlying tissue gets frozen, Blake's entire body is frostbitten.
