In 1999, a series of tragic events threatened to rip apart a close-knit circle of friends - and their small blue-collar town of Millwood, Pennsylvania. Twenty years later, a ragtag group of Millwood High students finds themselves hunted by an assailant known only as "A," who threatens to make them pay for their parents' past transgressions - as well as sins of their own. Created by Roberto Aguirre-Sacasa (Riverdale) and Lindsay Calhoon Bring (Chilling Adventures of Sabrina).
