The Other Side of the Door (2016 film)

The shamans begin to crowd the house; the possessed Lucy kills the family dog with a knife and stabs a horrified Michael. Maria breaks out and heads up to Oliver's room where she sees shamans chanting over Lucy's body. Since they cannot remove the spirit from Lucy, they plan to sacrifice her. However, Michael stops them and Maria tells Oliver that he needs to leave. Oliver says he is scared, but Maria says she will go with him. Oliver's spirit leaves Lucy's body and enters Maria's. She charges the shaman with the knife telling him to take her instead. He obliges, fatally stabbing her. She falls and awakens in the room alone. Myrtu appears and takes Maria to the afterlife.
