Part psychological thriller and part character study, A TEACHER explores the unraveling of a high school educator, Diana (Lindsay Burdge), after she begins an affair with one of her teenage students, Eric (Will Brittain). What starts as a seemingly innocent fling gets increasingly intricate and dangerous as her own emotions fully absorbed the Diana, crossing boundaries and behaving out in ways that are increasingly startling. Lindsay Burdge delivers a and compelling naturalistic performance that brings us.
