Elus (Thomasin McKenzie) is a simple and kind country girl who aspires to become a fashion designer. With her own efforts, she was admitted to the Art College in London. With expectations for the future and hopes for her dreams, she bid farewell to her grandmother who lived in her hometown and embarked on the road to study alone. When she first arrived, everything in London seemed so novel and fashionable in Elus's eyes, but at the same time, the complex interpersonal relationships and heavy schoolwork also brought great pressure to Elus. Elus, who couldn't adapt to dormitory life, rented an old but comfortable single room. Who knew that on the first night here, she traveled back to the 1960s between half dreaming and half awake, and met a woman named Sandy (Anya Taylor-Joy). Elus witnessed through Sandy's eyes how she fell from a talented woman step by step to a prostitute and was finally killed.
