After losing her son Oliver in a car accident in India, Maria has not recovered from the tragedy. During the accident, Maria chose to save her youngest daughter, Lucy instead of Oliver and the guilt devastated her. One night, her husband Michael finds Maria unconscious after a failed suicide attempt. In the hospital, Maria is comforted by her housekeeper Piki. Piki asks Maria if she wants one final chance to say goodbye to Oliver. She explains that in her village, there is an abandoned temple where the line between the living and the dead is very thin. Maria must scatter her son’s ashes at the temple steps and lock herself in. Oliver will speak to her once night falls. However, no matter what Oliver says, Maria must not open the temple door for him. Maria agrees and the pair have Oliver’s body exhumed and burned. Maria notices some strange men covered in ash. Piki explains that they are shamans (Aghori) who consume the flesh of the dead and coat themselves in ash to strengthen their bonds between the worlds of the living and the dead.
The next day Maria arrives at the temple and follows Piki’s instructions. Inside, she uncovers a mummified corpse of a woman. Night falls and Oliver begins talking to Maria, who apologizes to Oliver for leaving him. Oliver starts pleading with Maria to open the door and explains that someone is taking him. Maria panics and opens the door, but sees no one. She returns home the next day; now having closure, she focuses her attention on Michael and Lucy, but doesn’t tell Piki that she opened the door. Strange things start happening; their piano plays itself and Lucy tells Maria that Oliver has come back and that he is hiding from someone. In Oliver’s room, a chair moves toward her, along with The Jungle Book, which Maria was reading to Oliver when he died, but never finished. Realizing Oliver wants her to finish the book, she does so. Piki notices that the nearby plants have started dying and begins to realize that Maria had disobeyed her instructions at the temple.
