So the story starts out in the woods or a forrest at a creepy old house and a young boy or girl finds a dead girl in the trunk of a small older gen hatchback. You end up finding out that the girl from the back of the hatchback was murdered and is a zombie. She and her new acquaintance the boy or girl that meets her in the woods go around the woods trying to escape. That’s all I really can remember. It was a fairly recent movie, last 5 to 10 years I think. Thanks!
