Plot
In Kingston, New York, Emily Parris decides to get back at classmate, Mary Warren, for ruining her school play audition. While Mary holds her audition, Emily steals her phone and publishes all of Mary's texts on her blog. Mary retaliates by calling Emily a "blog whore" in front of the whole school, which lands both girls a meeting with the guidance counselor, Gordy Gambhir, in his office.
Later that night, Mary writes on Facebook that she will be taking a "vow of silence" and deletes her social media accounts. She forms the idea to create a "Sisterhood", and recruits classmates Catherine Huang and Lavinia Hall as its first members. Together, the three girls venture into the forest at night, beginning their ritual.
By the following school year, the Sisterhood has become common knowledge among school and all girls wish to join. However, no one knows what the group ritual is due to a vow of silence each member takes. New members are chosen by Mary and given a paper square as an invite. Emily, upset about being rejected, follows the girls into the woods and hides as the group ritual begins. While snapping a photo, she gets spotted by Mary.
