On the spookiest day of all, the night of Halloween, Lorina and her friends throw an exuberant house party. In the town of Nitun, the boundaries between jokes and seriousness, between fear and danger, are particularly blurred on this night. Lorina wants to get home on time so as not to worry her parents, because everyone knows that inexplicable and dark things can happen on this night. She decides to take the bus to be on the safe side. But while she is waiting for the bus, she observes a mysterious man on the other side of the street. His stare makes her blood run cold, especially as her vision is blurred by the loss of her contact lenses and the fog swirling around her.
