Neuropathologist Astrid Johansen doesn't know if she's going insane or if the monsters stalking her are real and something she can't explain. After the death of her mother, Ingrid, old wounds are reopened and the town's resentment against her family resurfaces, forcing her to navigate her complicated feelings about her late mother and her suspicions against her father... all while trying to protect her son... and prevent him from inheriting a dark family legacy.
