The title of the film doesn't make sense because there isn't a stepdaughter but a biological daughter, who went looking for her real mother who gave her up as a child. The radio on the edge of the bath is always death waiting to happen. Dumping a body in the boot of a car and pushing it into the lake is another. Wearing wigs, owning a creepy doll, and going by different names. The film dragged but soon after.an hour, after killing the mother, the rest is boring.
