Passion spirals into obsession when two women venture to a secluded cottage in North West Wales with a mysterious past. Haunted model Maria's marriage is on the rocks when she agrees to join reclusive photographer Francesca for a trip to the coast of Wales. Later, as Maria steps in front of Francesca's lens, her spirits begin to lift and her confidence is slowly restored. What Maria doesn't see, however, is that Francesca suffers from severe OCD, and that her fixation with the ravishing model is quickly snowballing into obsession. Meanwhile, something in the house has a hold on both women, and refuses to let go.
