Vivian Yin is dead. Now her remaining family members are gathered for the reading of her will and her daughters expect to inherit their childhood home. But due to a last-minute change to the will, the house is passed on to another family instead --- one that has suddenly returned after decades of estrangement. In hopes of staking their claim, both families move into the mansion. As Vivian’s daughters race to piece together what happened in the last weeks of their mother’s life, disturbing visions and bizarre behaviors start to take hold of everyone in the house, forcing them to realize they are being haunted by something far more sinister and vengeful than their regrets. After so many years of silence, will the families finally confront the painful truth behind the house’s origins and the last, tragic summer they spent there --- or will they cling to their secrets until it’s too late?
