Dementia 13 (2017)

Follows an old-money family who are still dealing with the youngest daughter's death several years later. While they are observing another anniversary of her death, a long con, an ax-wielding serial killer, and a vengeful ghost all coalesce on the same night to target the family. Everyone in the family has a secret, nobody wants to face what they did, and for someone to survive, the truth needs to come out--sooner than later.
