Mulder and Scully go into separate rooms to interview Margi and Terri, both of whom offer an identical story about a satanic ceremony where a baby was sacrificed. Scully thinks their stories are cliché and points out that no account of a satanic conspiracy has been validated. Looking at the latest victim's body, Mulder and Detective White find a burn mark in the shape of a horned beast; Scully says she doesn't see anything. Mulder goes to see White to apologize for Scully's behavior and the two visit the local astrologist Madame Zirinka who claims the town's crazy behavior is due to the rare planetary alignment of the planets Mars, Uranus, and Mercury. Terri and Margi watch basketball practice, lusting over one of the players, Scott, whose girlfriend is fellow cheerleader Brenda (much to Terri and Margi's displeasure). One of the other players accidentally spills a table of drinks on them, so they cause the basketball to bounce underneath the bleachers and it closes when he goes to get it, killing him. Scully is angry at Mulder for ditching her to be with Detective White. A town mob searches for a mass grave in the woods and finds a bag belonging to the town pediatrician filled with bones, which Spitz assumes belonged to a child. The angry mob goes to see the doctor, who claims that he had sold the bag to Terri Roberts. The bones end up belonging to Terri's dog, Mr. Tippy. Scully gets upset over a joke Mulder makes and tells him she's returning to Washington. Margi and Terri celebrate their birthday and Brenda uses a Ouija board to know who she will marry; everyone thinks it's Scott before the planchette veers away from the C and spells out Satan. Upset, Brenda rushes to the bathroom where Margi and Terri are chanting "Bloody Mary" and is locked in, killed by glass from a shattered mirror. Detective White heads to Mulder's hotel room because she found a box which inside had her cat's collar, and then she attempts to seduce Mulder but they are interrupted by Scully who informs them about Brenda's death. Terri and Margi try to console Scott, who tells them off. Turned down, Terri is mad at him but Margi still likes him and leaves. Mulder goes to visit Madame Zirinka again, who tells him that the planets come into alignment like this only once
