## Plot

### Act 1

The Machine G.A.P. hosts a Christmas party in a remote mountaintop cabin, inviting members of his company, Delta Seven, and Han Sorim. Veronica and Mone of the Flora Maid Service also attend to serve the guests. The Machine G.A.P. begins the banquet by telling the legend of the "Killer of the Holy Night," an evil spirit-like entity who appears every Christmas in the very cabin they are all in. The Killer would possess a random inhabitant, driving them insane and then using them to kill all the others inside. Sylvia Cooper and Jake Walker are unnerved by the story, but Kyle derides them for apparently believing in ghosts before reminding them that they are on a clandestine mission to uncover whatever secrets Coffin Company may hold.

Seo Yoon and Joo Shiyoon are the only ones from their respective squads that attend the party; Yoon couldn't bring the rest of ALT Squad along due to expenses, while Shiyoon stole their Vice President's password to her security account to gain approval for sick leave. As Shiyoon confides to Yoon what the password is, Alex overhears their conversation before introducing herself as someone with a "special relationship" to their boss as well as the one who provided the "exhibitory sculptures" — an Old Admin. Rifleman and Shieldman — for the party. The Machine G.A.P. then takes Alex away for a private conversation, and Yoon finds Alex's seductive attitude towards him amusing.

The lights in the cabin briefly go out as the Flora Maid Service prepares a show for the guests. But when they turn back on, Kyle suddenly goes berserk and attacks everyone while claiming to be the Killer of the Holy Night. Jake incapacitates him, and then the Machine G.A.P notices a handwritten "X" on Kyle's forehead, the mark of the Killer of the Holy Night. G.A.P. says that those who receive the mark will forever be cursed and suggests capturing the Killer in order to find a way to remove the mark. As the Killer is not an actual ghost, G.A.P. also believes that the real perpetrator is someone among the guests— however, he refuses to disclose who he thinks it is. He then orders everyone to go to their rooms and come back in thirty minutes, encouraging the Killer to privately come to him and confess.

Sylvia is exasperated while Jake decides to go talk to the Machine G.A.P once more. Meanwhile, Shiyoon spills his coffee and goes to the bathroom to find cleaning supplies, leaving Yoon behind.

About thirty minutes later, most of the guests return to the main hall. The Machine G.A.P. and Jake soon follow, but they too had been marked by the Killer. After taking both of them down, the others begin checking their alibis— Yoon and Shiyoon were together in their room; Veronica and Mone were rehearsing their performance; and Sorim had taken a nap while she hung onto Alex; but Sylvia, on the other hand, cannot prove that she stayed in her room as Jake, her only corroborating witness, is now unconscious. Now at her limit, Sylvia turns on Shiyoon by exposing his ability to hypnotize people (as Kyle had mentioned in a report) before attacking him with Leaf Node. In response, Shiyoon, Alex and Yoon quickly subdue and lock her up in a guest room.

Afterwards, Yoon confronts Shiyoon as she too suspects him of being the Killer. When Yoon points out that he did not get rid of the coffee stains on his suit, Shiyoon seemingly reveals himself as the culprit to her before attacking.

### Act 2

Sylvia, whose restraints were loosened secretly by Yoon, breaks free and helps Yoon fight Shiyoon. Veronica and Mone soon appear, but Shiyoon escapes before they can engage him. Sylvia and Yoon explain the situation, but Veronica is not entirely convinced the Shiyoon is truly the Killer because the Machine G.A.P. had placed so much trust in him. Not too long after, they hear screams coming from the reception hall and hastily make their way there. Han Sorim, the latest victim of the Killer, goes on firing spree with her rifle before taken down by the guests. Shiyoon is indeed present as well but flees after distracting the others by making the ceiling collapse.

The remaining guests discuss their plan on how to capture Shiyoon while Alex briefly checks their perimeter. Subsequently, the fallen victims have risen but remain hostile. Yoon and Sylvia break away to look for Shiyoon while the others stand their ground and stall their attackers.

Yoon and Sylvia eventually find and engage Shiyoon. Sylvia, under Yoon's request, creates a powerful EMP blast in their area, slowing Shiyoon down enough for them to subdue him. Sylvia is relieved that they caught the Killer of the Holy Night, but Yoon thinks the mystery has not been fully solved yet. Alex then barges in to warn the two that Veronica and Mone are now possessed as well before the maids follow behind and attack. The three women take Shiyoon and flee, and Yoon reveals Shiyoon was in fact just another victim after spotting the mark of the Killer on his forehead; she had suspected this earlier and thus had Sylvia launch an EMP attack to confirm it and sever the connection allowing the real culprit to control Shiyoon.

Yoon leads Sylvia and Alex to a safe location and asks Alex about how the maids became possessed. When Alex claimed they inexplicably turned after Jake snuck behind and knocked them out, Yoon subsequently concludes that Alex is the real Killer— firstly, Sorim could not have known if Alex had stayed in their room together if she was asleep during the thirty-minute break, thus creating a hole in Alex's alibi; secondly, Shiyoon targeted Sorim while Alex was still with the latter, thus raising the possibility that Alex was actually the one who marked Sorim; thirdly, contrary to Alex's claim, Jake would never attack anyone from behind even if he wanted to and only fights his opponents head-on; and lastly, before going after Shiyoon for the last time, Yoon says she left a listening device with Veronica that would confirm Alex culpability once they go retrieve it. Cornered, Alex admits to being the Killer of the Holy Night, only for Yoon to reveal that the last bit was a bluff and the device cannot record anything.

Yoon and Sylvia prepare to apprehend Alex, but Alex uses one last trick and brings forth the her "sculptures," which are in fact living soldiers, to aid her. The room begins to change form in a similar manner to the hyperdepths of the Counterside, making Yoon realize that the whole cabin had been not only set up to simulate the Counterside but also enable Alex to create illusions and warp the space within it. Yoon states that the illusions can be disrupted all at once with a strong EMP, so she takes Sylvia to the Machine G.A.P. so the latter can use his batteries to boost Leaf Node with enough power to create one. After Yoon uses the security password to reset the G.A.P. to its factory settings, Sylvia charges Leaf Node up and generates an EMP blast mere seconds after Alex and her soldiers catch up to them.

Moments later, Sylvia wakes up and sees Lee Sooyeon, who had arrived at the cabin via the Coffin. Sylvia also finds Jake and Kyle up and awake and tries to explain what happened while they were out, but neither of them believe her. Sooyeon dismisses her claims as well, even denying that she knows anyone named Alex, and tells everyone outside Coffin Company to leave the premises. Sooyeon then confronts Shiyoon and Yoon about how her security password was used to reset the Machine G.A.P., informing them they will be interrogated later, before sending them home as well.

Afterwards, the Administrator and Lyudmila arrive at the cabin as well to scold Alex for going overboard with her prank. Lyudmila feels partly responsible for not paying enough attention to her soldiers, though the Administrator also takes some blame as he was the one who asked her to create the cabin inside her Shadow World just to avoid paying a rental fee. The Administrator asks Alex about the Killer of the Holy Night and how she managed to hack into the Machine G.A.P. Alex explains that it was a game that she and the others played while they were serving the Old Administration as a way to recruit new soldiers; she got into the Machine G.A.P. after overhearing the password get mentioned during the party. Alex tries to get Sooyeon to explain what the password means, but the Administrator convinces her to let it go by treating all of Maze Division to dinner.

As Lyudmila creates a new log, she detects the Freedom Riders, which got lost while trying to reach the cabin, stranded in the middle of the blizzard and goes out to rescue them.
