Tijdens een bittere winter in Massachusetts in 1964 raakt de jonge secretaresse Eileen betoverd door Rebecca, de glamoureuze nieuwe raadgever in de gevangenis waar ze werkt. Hun ontluikende vriendschap neemt een vreemde wending wanneer Rebecca een duister geheim onthult, waardoor Eileen op een sinister pad terechtkomt.
