One night in 1989, Dylan Jacobs, a dumb boy with asthma, finds his mother crying in the kitchen with a lighted candle nearby. In the fall of the same year, Dylan and his father moved into a new house. In one of the rooms, Dylan finds a dusty mirror and an old book that contains instructions for invoking a spirit that is said to fulfill a wish of the one who invokes. It also specifies that at one o’clock before midnight the one who invokes the spirit must put three drops of blood in the wax of a lighted candle and place his wish in front of a mirror. The spirit will fulfill the desire at midnight if the person invoking it has an iron will. The problem is that the fulfillment of the desire could cost the one who invokes the spirit his own soul!
