Here is the official synopsis of episode 4:

After the latest attack by The Green Meanie leaves everyone shocked and saddened, Dean Munsch and Denise, along with Hester, devise a plan to catch the killer by throwing a Halloween party in the hospital. Meanwhile, Chanel celebrates a different kind of Chanel-O-Ween and attempts to make contact with the killer's latest victim from beyond the grave. Once the party begins, an outbreak surprises the hospital, leading Brock and Cassidy to jump into action, and another victim falls

Worried about the constant murders at the hand of a killer who leaves green slime as a trail of his gruesome crime, Munsch will seek the help of Hester, the former Red Devil aka serial killer of season one. In the promo released by Fox, Hester warns of massacres in the hospital and says: "On Halloween nights, massacres happen in this hospital. This year, it's gonna be a doosie."

Previously, the premiere episode revealed a little bit of history of the creepy hospital which goes back to 1985, where a pregnant woman interrupts a Halloween party to seek medical help for her husband. But instead of attending the patient, the doctor and the nurse injected aesthetic to him and dumped his body in the hospital's backyard swamp. It remains to be seen, how the incident is related to the present day killings in Munsch's hospital.
