Emily has six siblings, but she was also close to her best friend, Lizzie Porter, who died nearly a year ago. Emily is still grieving; Lizzie's family are grieving so much that they use Lizzie's younger sister, Chloe, as a lure and kidnap Emily, forcing her to dress, talk, and act like Lizzie. The Porters threaten to go after Emily's family if she does not become the replacement for the daughter they lost. Emily is caught between fear for herself and her family, and concern for Chloe, who she sees is also a victim of Mrs. Porter's madness.
