Jon Hamm and some guy are in a cabin together. Jon Hamm is a pearly-toothed American who wants to be friends. Other guy wants to keep to himself and is English. Oh, and he hates the clock on the wall. And he hates "I Wish It Could Be Christmas Everyday" by Wizzard. He has a good reason for this.
Jon Hamm breaks the ice by revealing he's a PUA coach who accidentally hooked one of his clients up with a crazy chick at a Christmas party who did a murder-suicide with him. This doesn't break the ice. So Jon Hamm reveals that PUA is just his side hustle and what he used to do was train "cookies." Cookies are virtual but sentient humans that are cloned from the consciousness of an original human. And his job is to break them mentally. Cookies are usually made to be virtual assistants to their original humans, but you wouldn't wanna do that forever, would you? So Jon Hamm has to break their wills. He does this with his enhanced interrogation techniques, bolstered by the fact that you can slow down a cookie's perception of time. He does this to a cookie by making her sit in silent isolation for 6 months. When in actual fact it was only a few seconds for us humans.
The English guy finally decides to open up. He had this fiancée, see, but they had a fight because she wanted to abort his kid. So she decides to "block" him. "Blocking" is this future feature where you can block someone IRL. He can't see her posts, she can't see his posts. By which I mean, in the outside world they appear as grey static silhouettes whose voices are warped and unintelligible. Joe is worried about the baby inside his ex-fiancée, so he spies and stalks his ex-fiancée. He can tell that, despite her just being a grey silhouette, she's still pregnant. She hasn't had the abortion. And so the English guy continues to stalk his ex-fiancée, visiting every Christmas. His ex gives birth and eventually raises a little girl. The little girl is also blocked from the English guy. And then his ex is killed in a train accident. With her death, the block is removed. He can see his daughter. And because his ex is no more, he would like to be in his daughter's life. So one Christmas he approaches his would-be father-in-law and says "Hey, I'm the baby daddy, I would like to be in my daughter's life." Oh, and "I Wish It Could Be Christmas Everyday" is playing on the radio. But his would-be father-in-law is like "No no you're not the baby daddy, my daughter had an affair with another man. The kid was never yours." Enraged, the English guy snaps and kills his would-be father-in-law. The little girl discovers her grandpa's corpse and goes out into the snow to get help. But she freezes to death.
It's at this point that the English guy recognizes that the clock on the wall is actually the clock from his would-be father-in-law's house. And the illusion is peeled back. The English guy was not the English guy after all, but a cookie cloned from the original English guy. And Jon Hamm was there to interrogate the cookie and get a confession out of it. The cabin was set up to subliminally trigger the memory of the crime. This is where the English guy/cookie recognized the clock he hated so much.
Jon Hamm is an excellent cookie interrogator. However, he is still guilty of PUA crimes or something. That guy died because of his PUA-ing. So Jon Hamm is sentenced to blocking. He is blocked by the entire world, and his silhouette, instead of grey, will be red. Noting that he is a sexual criminal and is to be avoided. The English guy will be tried in court for the murder. And the cookie? Well, because he's a cookie, humans don't think much of him. So the cops at the station fuck with him. They change his perception of time so that for every one minute that passes for us, 1,000 years passes for him. And they forget to switch it off. They decide they'll switch the perception back to normal when they get back from Christmas break. However, the radio was left on when they did this. And what was playing? "I Wish It Could Be Christmas Everyday." So there's the cookie. Trapped in the memory of the day he killed the old guy and subsequently led the little girl to her frozen death, forced to listen to the song that reminds him of it for... let's see one minute = 1,000 years, the cops won't be back to turn the radio off and fix time for at least a couple days... that's 1,440,000 years of Christmas per day in cookie time.
