The Favourite Sister is about a group of highly successful women who are participating in a reality show that ostensibly celebrates feminism. In truth, this series is a horror-show about pitting women against one another, making them feel insecure about their futures, and actively sabotages them if they ever leave the show. The result is a situation where feminist icons are put on unsteady ground, pressured to viciously compete, and then judged for competing as fiercely as they can. This leads to at least one mental breakdown, as well as at least one murder.
