A flu-stricken Buffy, reluctant to stay at home, patrols the cemetery. Xander, Willow and Cordelia surprise her and she nearly stakes Xander. They try to convince her to go home, but the damage that Angelus has done so far continues to fuel her fire. Angelus appears behind her and attacks Cordelia. Buffy and Angelus fight until Angelus pins Buffy down. Willow throws a burlap sack over his head, and he is scared off by crosses that they all carry. Buffy faints and the gang rush her to the hospital. After being stabilized, she is admitted to the hospital for a few days against her will. Her mother reveals that Buffy has always hated hospitals ever since her cousin died in one while Buffy was there with her.
Joyce brings up the topic of Ms. Calendar's death to Giles, and unknowingly brings up a topic Giles would much rather forget. Meanwhile, Xander, Willow and Cordelia wait to protect a very sick Buffy from the harms of Angelus. That night, Buffy has a dream where she sees a small boy standing in her doorway (this is Ryan, whom we see later). He leaves. A strange-looking man, not quite human, follows after him, glancing into Buffy's room as he goes. As she follows the man down the hall, flashbacks of her cousin's time spent in the hospital are brought to mind. She awakes suddenly in the middle of the night and takes a walk down the hall. Two men exit the children's ward with a child that died that night. At the door she overhears a conversation between Dr. Backer and Dr. Wilkinson about the doctors' experimental treatments on the kids. As she begins to leave, she encounters two children that tell her about "Death" and how he comes at night.
That night, Angelus comes to visit Buffy but Xander stands guard. They stand face to face and exchange many harsh words until Angelus finally leaves discouraged by the fact that he may not make it to Buffy's room with all the security. The next morning Buffy's friends visit bearing gifts to cheer her up — all but Cordelia, that is. They all take a walk and Buffy tells them all about the conversation she overheard. The doctor was trying experimental treatments on the kids in the children's ward that Dr. Wilkinson didn't exactly agree with. Since forced to stay at the hospital she plans to find out what the doctor is up to and Xander volunteers everyone's help. Cordelia and Xander sneak into the hospital's record room and search for records on the girl that died that night. Meanwhile, Giles and Willow search for information at the school library. While looking through the records, Cordelia is caught by the security guard. She flirts with him until Xander can escape with the records, then leaves herself. Xander expresses his feelings towards her flirting with him and Cordelia expresses her anger about Xander's behavior around Buffy. Jealously she leaves to take the records to Giles and Xander "watches her back" as she goes.
Buffy takes a walk and finds the little boy. He is drawing a picture of the man she saw in her dream. Willow digs up information on Dr. Backer at the library with Giles. She finds that he has a large past of experimental treatments and investigations into his practices. Meanwhile, Dr. Backer is working on trying to cure the children's illnesses. After finding a solution that he thinks will work, he takes it to the children's ward to try it out. Before he can do anything, the evil creature attacks him and slashes him up. Buffy tries to stop him but is thrown aside unable to see the creature as its invisible.
The next morning Buffy informs everyone that Dr. Backer is not the suspect and shows them the drawing that Ryan drew of the creature. Xander, Giles and Cordelia leave her alone and come up with a plan. Giles and Cordelia head back to the library while Xander stands guard against the threat of Angelus. At the library, Cordelia annoys Giles with constant questions. Finally, she finds a picture of the monster on the cover of a book and they research it. After searching they find that it is called Der Kindestod. After Cordelia squeamishly describes what is going on Giles takes over and then tells Buffy about how it sucks the life out of a child. Buffy flashes back to her time at the hospital as a child again. She sees her cousin freaking out while she helplessly watches. Buffy goes silent over the phone and then after several minutes, Willow takes it from her and hangs up. Buffy then realizes that Der Kindestod was the killer of her cousin.
The two head to Dr. Backer's office in search of answers. They find out that Dr. Backer was giving the children injections of the disease they already have in order to inoculate them against it. Buffy realizes that only sick people can see the demon, so decides to infect her self with the vials of disease the doctor was using on the children. Willow stops her, warning her that the vials are 100% pure and would kill Buffy instantly if she drinks them. Willow then dilutes the disease in some water so Buffy can drink it "safely". Buffy's fever rushes to a near 107 degrees as she stumbles to the children's ward. She finds all the children are gone. They have headed down to the basement in hopes of escaping from the Kindestod. After a few moments, Buffy sees the Kindestod in the room and watches as he heads down to the basement. The door is locked so Buffy and Willow rush to find access to the basement. Dr. Wilkinson tries to stop them, but Buffy shoves her aside. When security guards stop the two, Willow takes on the blame as Buffy makes her escape.
Buffy works her way to Xander, and he helps her down to the basement. The children wait quietly in hopes of not being found, but then the Kindestod picks up Ryan. He screams, along with all the other children. Buffy arrives just in time and fights off the Kindestod. Just as he is about to kill her, she snaps his neck, and then leaves while leaning on Xander. Buffy finishes her rehabilitation at home with her friends. Her mother reluctantly waits on them all. Joyce then hands Buffy a letter from Ryan, which is revealed to be a drawing of her hailing over a dead Kindestod.
- Artistic Licence Medicine: Buffy reinfects herself with the same flu strain she already had, in order to get a fever that allows her to see the demon. After her immune system got rid of her flu infection earlier, she would be forever immune against that particular strain, and it would take at least a day to kick in anyway. This plot point would have made a lot more sense if Willow had figured out which drug from the hospital pharmacy to use to artificially raise Buffy's temperature.
- Also, the doctor's strategy of curing the kids by increasing their viral load and so making their fever spike is complete nonsense. Raising the body's temperature higher and higher in a futile effort to "kill" the virus is exactly why and how some rare strains of the flu (such as the famously deadly Spanish flu) kill especially young people with active immune systems - it's their own fever reaction that kills them, not harm done directly by the virus.note (The fever defense strategy of the human body only really works against organisms that really are alive and have a metabolism to disrupt through the heat, like bacteria.) Short of actual antiviral medication, the most sensible way to treat a viral infection like the flu is to keep the body's fever defense mechanism in check, so that the body doesn't cook its own cells, and to try and ward off additional bacterial infections, thus giving the immune system enough time to produce antibodies specifically designed to bond and catch the virus particles. It really is mostly just a matter of waiting it out.

- Improvised Weapon: Willow throws Xander's jacket over Angelus' head, whereupon Xander grabs the blinded vampire and delivers some Percussive Therapy of his own.
- Innocent Innuendo: Willow mentions that she and Xander used to play doctor. She would get out medical books and diagnose him with things. Xander didn't have the heart to tell her she was doing it wrong.
- Innocuously Important Episode: Buffy is sick and ends up in hospital - a place she hates since her cousin died in a hospital when they were children. While the Monster of the Week in the episode (which was also responsible for her cousin's death) is dealt with, Sunnydale General ends up playing a big role in Season Five - not only does Buffy's mother Joyce end up with a brain tumor and spends a few episodes there, but we're also, at the same time, introduced to the character Ben Wilkinson, a young medical intern who serves as a possible Love Interest to Buffy and who turns out to be the mortal, human shell of Glory, the Big Bad of Season Five - Glory's plans, in turn, result in Buffy's death in the Season Five finale.

- Long-Lost Uncle Aesop: Buffy exhibits a phobic reaction to being in the hospital, and we learn that it's because of her cousin Celia's death when they were kids. They were close, and Buffy was traumatized as a result of watching her die. While some of this trauma is legitimately resolved in the episode, the lack of mention of Celia before or after makes the whole thing seem to come out of nowhere. It is particularly jarring because Buffy spends a great deal of time visiting the hospital in Season Five, and shows no phobia beyond an appropriate reaction to the immediate circumstances. Then again understanding (and killing) the cause of her trauma would've allowed Buffy to get over it.

She's sick, make it better!
