Black Mirror season 7 episode 2
Episode title: Bête Noire
Maria is a high-flying development executive at a chocolate company. Everything is going well for her until someone she hasn’t seen since school — a woman named Verity — shows up for a focus group tasting session. It could be the chance for a heartfelt reunion, except there’s something very odd about Verity, and Maria seems to be the only person who notices.
