American sisters Laura (Natalie Portman) and Kate Barlow (Lily-Rose Depp) conduct séances at a nightclub in 1930s Paris, and are soon approached by French film producer André Korben (Emmanuel Salinger). Eager to learn how they perform their occult tricks, Korben is shocked to realize the siblings may really be communicating with another dimension, and he sets out to make them stars. Meanwhile, the relationship between the sisters flounders as André's attention sets them on different paths. Directed by Rebecca Zlotowski.
