Three young women, strangers to one other, end up living together in Paris in tiny rundown rooms atop of a middle-class apartment building. There's Suzanne, a strong-willed streamer who’s been kicked out by her father; Saskia, an upcoming artist discouraged by a mean gallery owner; and Anne-Lise, who comes from an intensely religious family. Strange and eerie events bring them together: ghostly apparitions disturb Suzanne’s video games, a spirit enters Saskia’s room, and voices invade Anne-Lise’s brain. They realize they all have personal problems—family, artistic, and spiritual—but decide to confront these together. Are these seemingly supernatural phenomena real? Or have the girls gone mad?
