Relic

When elderly mother Edna inexplicably vanishes, her daughter Kay and granddaughter Sam travel to their remote family home to look for her. They discover the house locked from the inside, and a strange black mould-like substance on an upstairs wall. Edna's neighbour Jamie visits them, and Sam experiences nightmares of a withered rotting corpse in an old shack in the woods. As they search for Edna, they uncover clues of her increasing dementia scattered around the house, and their own family dynamics are put to the test.
