The upcoming episode of "American Horror Story: Hotel" will be a continuation of the previous Halloween-themed episode, which saw a number of notorious serial killers checking into Hotel Cortez for a dinner from hell.

The previous episode also saw Alex taking The Countess up on her offer to become a vampire so that she could spend eternity with her son, Holden.

But it looks like the thirst for immortality will get in the way of her profession. A promo video for "Room Service" shows Alex visiting one of her patients whose health is on a downward spiral.

"They asked me to sign a DNR," the patient's mother tells Alex. "Please tell me that we're not there yet."

However, Alex can't seem to focus on her patient; she is distracted by the pulsing vein on the mother's neck. But she manages to assure the mother that she will figure out a way to save her son, and based on the synopsis it looks like Alex will resort to some unconventional method.

Meanwhile, her husband is out to figure out the truth behind the dinner that had history's notorious serial killers as guests. Although Sally tried to convince John that he was hallucinating, he is committed to stripping "those walls down to the studs" if need be to find out about the mysterious guests at Hotel Cortez.

"Room Service" will also focus on Iris, who has been brought back from the dead by her son Donovan, and their plan to take down Lady Gaga's The Countess.

"American Horror Story: Hotel" episode 5 will be aired on Wednesday, 4 November at 10 p.m. EDT. Click here to watch the episode online.

The official synopsis for the episode reads:

Alex uses an unconventional treatment to save a dying patient. A Halloween-hating couple test Iris' limits.
