Relic, the film directed by Natalie Erika James, follows the story of three generations of women from the same family (mother, daughter and grandmother), who find themselves together in a mysterious ruined house, where something terrifying takes over.
Edna (Robyn Nevin) is an elderly widow suffering from senile dementia. When suddenly the woman disappears from her, her daughter Kay (Emily Mortimer) and niece Sam (Bella Heathcote), they run to look for her and go to the old family home in the countryside. Once there, Kay and Sam find numerous traces of Edna's growing and serious illness scattered around the house.
The old woman suddenly and mysteriously reappears, just as she was gone, but she is unable or unwilling to say where she has been. While her daughter seems to be bothered by this attitude, her granddaughter is happy to finally hug her grandmother again.
Unfortunately, Edna's behavior becomes increasingly worrying, Kay and Sam begin to suspect that the house is inhabited by a strange and dangerous presence that could haunt the old woman.
