Mary Loss of Soul (2014) on Netflix

Plot summary

Fifteen year old Mary Solis disappears from her family's lake house one night and comes back with no memory of that night and with a part of her soul missing. The Solis family, Victor, Gina and Mary's sister Sophia, has a girl at home who is not entirely whole, and no one has an explanation for it. Mary's disembodied soul begins a haunting, and the family's deepest fear is watching her fade. No one can say whether what has happened to Mary falls under a centuries old condition called loss of soul, or whether something more malicious is at work.
