Watched it on LifeTime many years ago. But I don’t think it was a LifeTime original. A new teen moved into a town. The house she moved into is huge and next to a small cemetery. Some teens befriend her. Turns out they were in a cult (or maybe witchcraft. Can’t remember which.) the teens were a mixture of boys and girls. The new girl figures out. The teens try to get her join. She refuses. They try a sacrifice. She ends up living. The ending ends with her standing in the small cemetery.
