A Teacher is a 2020 American drama miniseries created by Hannah Fidell and starring Kate Mara and Nick Robinson, in which Claire Wilson — a thirty-something high school English teacher in Texas, unhappily married to her college sweetheart Matt — begins grooming and manipulating Eric Walker, a popular and charming seventeen-year-old senior in her class, into a secret sexual affair. What Claire frames as a passionate forbidden romance is slowly revealed to be a predatory abuse of power — the series tracking the relationship from its charged beginning through Claire's arrest, Eric's destroyed reputation going into college, and the long-lasting psychological damage inflicted on both their lives, following them years into the future.
