The "girl" is actually a woman, heavily pregnant and fleeing her abusive boyfriend that is also a killer. Ava the pregnant girlfriend tries to flee but there is a storm at night and she loses control of the car. She wakes up in a large cold looking spider web of a house, with a weird couple, while she's due to give birth. I found this tense and watchable. It wasn't "predictable" as some reviewers have said, because there are many twists and turns.
