The story seems to be about two sisters, who, upon returning to their father's home after some sort of absence (later revealed to have been a stay in a mental institution) are forced to deal with not only a seemingly schizophrenic and possibly bi-polar stepmother who lashes out at the younger of the girls when the mood strikes her and cheerfully tells them she's prepared a special dinner at another time., but some presence as yet unexplained.
