Although Camille and Helina expect another prank, the group is stunned when they actually make contact with a spirit, which warns them that they will be murdered.

The next day, Mrs. Landry questions the girls on Lenora's unusual disappearance, and informs them her personal items are missing, suspecting she has run away.

The group investigates her room with Trevor's help, and discovers a strange cross drawn in blood on Lenora's bed.

Camille later identifies the cross as a symbol on a pendant worn by Alicia Kane, the deceased student who supposedly became the Edelvine Ghost.

Camille, Helina, Alice, Bethany, and Yvonne meet for another seance to contact Rosalind, and ask her what happened.

Alice receives a text from Yvonne asking her to go outside where she discovers Lenora's corpse before being knocked out by the masked assailant.

Camille kisses Helina, waving both her and Kerrie's ghost goodbye before leaving the academy campus.

In October 2019, it was announced Suki Waterhouse had joined the cast of the film, with Simon Barrett directing from a screenplay he wrote.

[5] The review aggregator website Rotten Tomatoes surveyed 35 critics and, categorizing the reviews as positive or negative, assessed 18 as positive and 17 as negative for a 51% rating with the consensus reading, "Writer-director Simon Barrett has a certain filmmaking flair, but it isn't enough to raise Seance above its somewhat pedestrian story".

[7] Lena Wilson with The New York Times said "when the film does choose a genre, it occasionally sticks the landing, but Seance ultimately feels jumbled".
