Fourteen-year-old Preston Craft is organizing a film festival for his school's film club. When one of the films goes missing two days before the festival begins, Preston is convinced it was stolen and is determined to get it back. The only indication of the theft is a suspicious shadow that Preston noticed right before he discovered the film was gone--but Preston is legally blind and no one quite believes him. However, not unlike the gritty private eyes in the classic black-and-white films he adores, Preston refuses to give up. Can he solve the mystery based on such a shady clue?
