Cleaning out her late mother's dusty, decrepit house, visiting her mentally deteriorating father at his care home, and supporting a bereaved woman at work only stirs up more emotional stress. Soon, her behavior is out of control. But while Catherine obsesses, she does not see the dangers in front of her, and both mother and daughter will be forced to deal with the painful truths that are keeping them trapped.
