Marbeley (2012)

When the spirit of Dr. Emmet Cole mysteriously enters Jahel, the message is clear: go home! Instead, Tess determines to go into the jungle to find clues to Cole's whereabouts. While on their mission, they discover a tree draped in children's dolls that they suspect is there to ward off the "spirit of the abandoned girl" who drowned in the river. Then, when a member of the crew goes missing, the group realize they'll have to endure a nightmare in order to appease an angry spirit and get their loved one back.
