Mama Quinn Brenner (Stefanie Scott) died a year and a half ago, but the teenage girl continues to feel her presence, although for the time being it does not bring any appreciable inconvenience and does not seem strange to her.
Quinn is in love with a peer-neighbor, and the guy responds to her in return. They often communicated by knocking through the common wall of two apartments, but in another such communication session, Quinn realizes that she is not the object of sympathy, but someone else.
With a young heroine things begin to happen that are beyond understanding. Her father (Dermot Mulroney) invites a famous psychic Alice Rainer (Lin Shaye), wanting to save her daughter from suffering and drive out the ghosts from their lives. The medium explains: when Quinn called for her dead mother, all the dead people heard this call immediately. Evil has come and devours the girl's soul, and Alice goes to the other side to bring everything into balance, but will it be enough effort?
