A family friend asks Elly to help care for an old woman who lives in a secluded cottage for a few days. She nods enthusiastically, believing that a quick excursion into the woods will be a pleasant respite. As Elly starts to experience hallucinations that mix her dreams and reality, the cabin proves to be anything from peaceful. Elly discovers that she was led there by a demonic force that was inside the woman and was only waiting to escape as the images start to take over.
