The story of two inseparable twin sisters, “Joan” and “Jean”, who live on the fringes of society. The film is inspired by the British identical twins Freda and Greta Chaplin, who had brief tabloid notoriety in the early 1980s when they became sexually infatuated with their nextdoor neighbour, a lorry driver, who eventually took out a restraining order against them. The Chaplins were the only known twins who spoke synchronously, and the film is titled after a verbal slip the twins made simultaneously when they were in court.
