The movie kicks off with some narration about the Christmas magic of snow in fairy tales. But this isn’t just any normal fairy tale.Cut to a house, all decorated for Christmas. The camera pans over to the house next door, which is dark and cold. Inside is Kathy, who is just as cold as her surroundings, while a truly awful version of "Jingle Bell Rock" plays in the background. We learn that Kathy runs a diner, and although her house may imply otherwise, she isn’t nearly as miserable as it seems. The diner keeps her busy, and she likes it that way.She goes to serve a couple some food, and they encourage her to get back out there. Before she leaves, they give her a scarf. While walking through the town square, Kathy comes across a very muscular snowman. She drapes the scarf around it and takes a picture.That night, the magic winds blow, and the snowman comes to life — with the long scarf still around his neck, if you catch my drift. He starts walking around town, taking in the sights and sounds, but soon realizes he’s not wearing any clothes. Desperate, he breaks into a store and grabs the first thing he finds to cover himself.The next day, Kathy parks her car and sees a man who appears to be talking to the other snowmen. He notices her and excitedly tells her what happened to him. She’s confused but invites him to her diner.Meanwhile, the police chief, Nate, investigates the break-in. "Stuff like this doesn’t happen in his town!" he declares, taking the case very seriously.Back at the diner, Kathy tries to figure out this guy’s name. The shirt he stole has "Jack" written on it, so they go with that. Jack explains that he was the snowman Kathy put the scarf on. Kathy thinks he’s crazy but also feels sorry for him since he’s freezing. She takes him to the doctor, who suggests that maybe Jack is telling the truth — who can say for sure? They discuss finding Jack a place to stay, but he insists on staying with Kathy because he feels safe with her.She reluctantly agrees, bringing him to her house and leaving him in front of the TV. After watching several channels, Jack snoops around her house and finds pictures of Kathy with a man and some medical forms about chemotherapy.That night, Kathy comes home and realizes that the police are looking for Jack. She tells him to lay low. In return, Jack shows her that he made homemade pizza crust and eggnog. He also asks her about her late husband, and she opens up to him.The next day, Jack finds the home improvement channel and decides to get to work fixing up Kathy’s house. But when a woman named Jane sees him shirtless, she crashes her car. She brings him to her house to help with repairs and later takes him to the diner, where Sheriff Nate is also present. He’s immediately suspicious of Jack and his strange habit of eating ice.Despite the sheriff’s suspicions, Kathy is moved by Jack’s hard work and enthusiasm. She tells him that he can help out at the school, where he quickly becomes a hit. Jack is loving life, and Kathy starts to enjoy his company, though she admits that she can’t love anyone until she learns to love herself first.As Jack helps decorate for the school’s Christmas ball, he realizes he wants to ask Kathy out. With some encouragement from Deputy Schatz, Jack finally works up the courage. After some hesitation, he tells Kathy, "I don’t want to lay low. I want to stand tall." She agrees, and they go fancy shopping and have a wonderful time.Later, they go to the school dance and have the best time of their lives. They step outside to cool off, and they almost kiss, but Jack pulls back. He says, "The more I fall in love with you, the more I can’t stand the thought of hurting you if I melt." They share a hug.On Christmas Eve, Kathy hosts a gathering at the diner. Suddenly, Sheriff Nate comes in and arrests Jack after finding a picture of him at the ATM. Kathy rushes to check on Jack and discovers he’s melting. She runs to get all the money in her safe, but it’s not enough. The townspeople, however, come together and contribute their own money — it’s a "It’s a Wonderful Life" moment. Sheriff Nate counts the money, but after seeing how much it means to the town, he returns it to Kathy.She rushes to Jack, who is in a bad state. The townspeople carry him out into the snow, but he doesn’t wake up. Desperate, Kathy leans down and tells Jack that she loves him before kissing him. She begins to walk away, but suddenly Jack stands up. They embrace, and Kathy notices something’s different. Jack says, "I don’t know what’s up," and shivers. Kathy exclaims, "You’re cold!" They kiss again as the crowd cheers.They spend Christmas together, repair the heating in her house, and then head off to Hawaii for a well-deserved vacation.
