A family, reeling after the death of one of their daughters, returns home early from vacation to reclaim their home from Rebecca, a seemingly pleasant house sitter. Since they returned early, Rebecca has nowhere to go, so the family invites her to stay. At first, Rebecca is a godsend—she cooks, cleans, and does laundry–but the family discovers that she is not as innocent as she appears. Now that they are back, she isn’t satisfied with simply being a guest… she wants to be a part of the family.
