Yet how can his scientific rationalism accept Heidi's belief in paranormal forces? If the alleged haunting turns out to be real, he'll have to change his entire worldview. Can their love flourish while coping with an exotic supernatural infestation? At least the creatures aren't dangerous—or are they?
