The World is Full of Secrets is a devilishly creepy film about a group of girls telling scary stories in the dark. An old woman's voice recalls a terrible event from her distant past: On a summer night in 1996, five teenage girls meet in a suburban house, absent of parental supervision. To pass the time, they begin to tell morbid stories of the world outside, trying to best one another in a grim competition. As the night becomes darker and their play becomes more serious, their world of fiction is consumed by reality in this feverish Decameron-in-miniature.
