According to the press release:
After India's (Mia Wasikowska's) father dies in an auto accident, her Uncle Charlie (Matthew Goode), who she never knew existed, comes to live with her and her emotionally unstable mother Evelyn (Nicole Kidman). Soon after his arrival, she comes to suspect this mysterious, charming man has ulterior motives, but instead of feeling outrage or horror, this friendless girl becomes increasingly infatuated with him.
Directed by Oldboy alum Chan-wook Park in his American film debut, Stoker premiered at Sundance to good reviews. As the GIFS show, the film definitely has Park's trademark sense of twisted forbidding.
