A Dark Song

Sofia rents a country mansion in the middle of nowhere and invites the occultist Joseph there for some dark ritual. At first he refuses to perform the ceremony, but upon learning that the woman lost her son and wants to communicate with him in this way, he agrees. Sofia buys food for six months, the occultist seals the house with a circle of salt, and now there is no turning back - no matter what happens, they must finish what they started before going outside.
