A mysterious entity will now follow her everywhere she goes, slowly walking toward her while taking the form of strangers, friends, or loved ones. The only way to escape the curse is to pass it on to someone else—but if the person ahead of you dies, the entity comes right back for you. As Jay and her friends try to understand the terrifying rules behind the curse, they realize that no matter where they hide, it is always getting closer.
