Christmas with the In-Laws

On a long, cold, winter's night, Emma and her girlfriend Kathy make the journey to visit Kathy's family for the holidays. Emma has never met Kathy's parents, though she has been wanting to for a long time. She has been warned about Kathy's mother Doreen and her high standards. Kathy is unusually nervous about the whole thing, and, when they arrive, she soon disappears for a "e;talk"e; with her mother. As Emma works to get on the family's good side, she starts to grow more suspicious -- why is Kathy sneaking away from family activities? And why was she talking to Doreen for so long?
