Juliette asks Sean where Adalind is and that she wants to kill her. He tells her that's a good idea and they have sex.

A mans car breaks down and he heads to the nearest house where a woman is on the phone with her daughter. The woman's daughter tells her not to open the door. The man, a snake-like Wesen, gets angry and attacks the woman, killing her.

Nick, Wu and Hank show up to the crime scene. They view the body which is frozen solid and determine the suspect is Wesen and has stolen her car.

Wu gets a lead of the suspect leaving a gas station in the victims vehicle and they set up a roadblock.

Monroe is working on a clock when he has a flashback of his kidnapping, shaking and unable to continue. Rosalee gets home and Monroe woged, scaring her. He apologizes and tells her that they never know how much time they have with each other, with Rosalee reassuring him that they can never take the time they have for granted.

The roadblock works and the suspect approaches, but makes a u-turn and is now being chased. Monroe, Nick and Wu block him off but he jumps out and runs into the woods. Nick's enhanced senses allow him to follow the suspect. The suspect stops and is shaking from the cold before he woged. The man sees that Nick is a Grimm and returns to his human form. He is freezing and changing colors.

Monroe is telling Rosalee about a clock when she hugs him. She asks him about what he was thinking of and he tells her about his flashback. She reassures him that they are safe now.

The suspect, Knute Gunderson, is from North Dakota. as they get ready to search what type of Wesen he is, They find that he died and is frozen solid.

Nick and Hank find Gunderson's car and sees old fast food containers, enough for three people.

Kenneth tries to find a way to locate Nick's mom and Adalind needs to find clothes because none of her other things will fit.

A woman stops her car when she sees a man freezing. He tries to attack her but she manages to get away.

Adalind is out shopping when she sees Juliette's reflection. Her bodyguard manages to push her out of the way of a concrete statue that Juliette attempted to kill her with.

Nick and Hank are in the trailer doing some research. Unable to find answers, they go to Monroe and Rosalee. They tell them about the Wesen that will freeze to death unless they take the heat from someone else.

Juliette shows up and they have a little argument. Juliette tells Rosalee and Monroe that she's a hexenbiest. She gets angry and blames all of them for what she has become and leaves. Nick tells them that there is no fixing things but Rosalee tells him that she is not giving up. Nick, Hank and Monroe leave after Wu tells them about another frozen body.

They reach the crime scene and Wu fills them in. The man is also from North Dakota, brothers with Knute. Wu goes to find out if there are any other Gunderson's in North Dakota While Nick and Hank look for any Gunderson's in Portland.

Anther man attacks a taxi driver and Hank calls the service to find that he was going to pick up someone at their spot. Wu finds out the third brother, Sven, is the Wesen that's still on the lose. They manage to find a Gunderson home in Portland and head that way.

Adalind complains to Kenneth about Juliette trying to kill her. He decides to use Juliette to find Nick's mom.

Nick, Hank, Wu and Monroe are at the Gunderson address. They sneak up to get a closer look but it doesn't seem as if anyone is home. They head inside and find it freezing. It starts to get warmer and they find a trap door where it's really hot. They head down and find multiple people huddled up in a pile, it's a Hibernaculum for the Wesen to keep warm.

They search for Sven in the pile of people and spot his tattoo. They try to get him out but they accidentally wake them up. They head up the stairs to get away. They go into a barn but they eventually get in and start to attack, but they start to freeze. Nick tells them to put everyone back because they're innocent. They take Sen's frozen body and put him back in the stolen taxi elsewhere.

Nick goes back home and stares at a picture of him and Juliette.
