Unforgettable tells the story of Tessa Connover, a woman who is barely coping with the end of her marriage. Her ex-husband, David soon becomes happily engaged to Julia Banks, not only bringing Julia into the home they once shared, but also into the life of their daughter, Lilly. Tessa’s jealousy soon takes a pathological turn until she will stop at nothing to turn Julia’s dream into her ultimate nightmare.

Unforgettable is due in theaters in 2016.
