Set in Los Angeles in the year 1967, we find a widowed scam artist named Alice, who is working from home as a spiritual medium to make ends meet for herself and her two misfit daughters, fifteen-year-old Lina and nine-year-old Doris. Inspired by a new 'board game' of sorts that has spooked Lina and her friends, Alice decides to incorporate a Ouija board into her flashy seance showcase, but things take a weird turn when it ends up that the device seems to actually be a portal into the spiritual world, one that might put the family in contact with their deceased father/husband. Alas, what they find on the other side is increasingly unnerving, and now young Doris is showing signs of becoming a conduit for malevolent forces to make the leap to the earthly realm.
