WARNING, SPOILERS AHEAD!

But take every thing I say with a grain of salt. A lot of this is speculation and the game isn't finished yet!

Beginning:

Our story starts with khan initiating a new and seemingly redundant security program that revolves around having new recruits watch the newly installed security cameras. For the sake of the plot your character (Lizzy) is the only one to sign up. Khan provides basic training for Lizzy and promises to give hourly updates on your tasks and any information you may need.

12:00 AM:

The game starts halfway through Lizzy's first night with an update from Khan giving Lizzy her final introductory to the Job. He tells you to watch the cameras for any suspicious behavior. Things start to pick up when Lizzy notices that one of the murder drones outside is missing. It doesn't take long to realize that he is now inside the bunker. As the hour progresses both of the murder drones will attempt to get into the office. You can defend yourself with the doors but the reason for their hostility remains a mystery.

1:00 AM:

At 1AM Khan makes Lizzy aware of a third murder drone who's half dead body has been stored in the janitorial closet. Although Khan informs Lizzy that she may wake up soon she never seems to move. About 20 minuets in you hear a strange noise coming from the vent ahead of you. You check the camera only to realize that khan's daughter Uzi isn't in in her room. Putting two and two together leads you to the conclusion that she must be crawling through the vents. Just to make sure you check the vent cam and lo and behold, there she is sitting in the vent and staring blankly at the camera with a strange symbol on her visor. Whatever is causing the murder drones sudden hostility must have spread to Uzi. Fortunately you find that wearing the WDF issued mask wards her off.

2:00 AM:

At 2AM khan tells Lizzy that he noticed Uzi's sudden behavior change and says that he is just as clueless about her aggression as you. Around this time you notice that J the third murder drone has opened her eyes. Khan was right after all. And worse yet she is just as aggressive as the others, if not more so.

3:00 AM:

When 3AM arrives Khan tells Lizzy that the team has been having difficulty with the cameras as well as noting the sudden disappearances of several worker drones around the colony. later on in the hour the same symbol that was on Uzi's visor appears on your camera screen, you assume that this is just a visual glitch with the camera feed and reset the cams to make it go away. however when it appears a second time you notice a strange reflection that appears to be the bottom of a drone's face. As it turs out this isn't a glitch but rather a person blocking the camera. 

4:00 AM

Khan calls Lizzy again for her 4AM update. He tells her that the team has also noticed the person obscuring the cameras. They also mention that your friend doll has gone missing within the last hour. It is more than likely that she is behind the obstructions but you still don't know why any of these adversaries are acting hostile all of the sudden. Before khan finishes the update he mentions that Uzi has just entered the room. But his excitement quickly turns to confusion and then fear as he notices Uzi edging closer to him. On the other end of the receiver you hear Khan's terrified scream followed by a loud metallic crash before the call is cut short.

5:00 AM:

At the turn of 5:00 a new voice calls Lizzy, not Khan but one of his subordinates instead. He says that Khan and many of the missing drones have turned up, but they have gone rouge and started attacking the WDF. According to him they have the ability to disable the doors. N V and Uzi are missing at this time and do not appear at all during this hour. Instead you are attacked by an onslaught of infected worker drones. At the conclusion of the night it will show the victory animation like normal, but halfway through it will be interrupted by a windows defender popup stating that the program preformed an illegal action. Note that this popup is FAKE and FHoC9 is NOT a virus. (Oh and it does save your progress btw. I was a little worried about that the first time I saw it.) after clicking "CLOSE" your game will crash.

606:00 AM:

Upon opening up the game again the logos and title screen will be skipped bringing you straight into the next hour. When you check the cameras you will notice that the time reads 606:00 AM. This is a reference to error 606 which is associated with absolute solver corruption. After a few seconds text will appear on screen that reads the following:

"It's me"

"I'm still alive"

"You have to listen"

"She has one weakness"

"Watching her stops her"

After this point Cyn will spawn in the warehouse shortly. This is it, the showdown with Cyn that you've been waiting for. If you do what the disembodied voice says and keep an eye on Cyn whenever possible her pace will be slowed to a crawl. During this hour Cyn is escorted to your office by Doll and Khan, no other characters are present. Dying during this hour will crash your game.

6:00 AM:

6AM serves as the game's custom hour. Normally nothing happens at the beginning of the hour. But if you set all enemies to level 20 you will be greeted by a phone call telling you to evacuate. For the sake of the plot Lizzy ignores the warnings. 

That's all the info I have right now.

Aftermath:

Sorry, I don't have any information on this yet. :(
