Based on the true and ancient rituals of sacrifice from the 13th century in Borneo, Jerunei tells the story of Dr. Sani and a team that goes in search of his wife, who disappeared on an expedition to study a mysterious Jerunei (Burial Pole). Combing through the jungle for answers, each member of Dr. Sani’s team faces hallucinations, malevolent disturbances and transported to strange places. Things take a turn for the worse when one of them is taken over by dark forces from beyond the Jerunei.
