Emmy Dockery is an FBI research analyst on leave. She has been obsessed with a large number of fires in which a single person always died, including one involving her sister. Local authorities, finding no foul play, ruled all these fires were accidental. New fires fitting the pattern claimed by Emmy continue to occur. No one believes Emmy and some even think she has gone mad. By continuing to insist these explained fires were really murders, she has put her career with the FBI in jeopardy. Even her ex-fiancé (nicknamed "Books"), who is an ex-FBI agent, doubts her. But one day she finds something of interest to Books and a preliminary investigation is launched by the FBI with Books in charge of the investigation and with Emmy on the team. Soon more is found and this case becomes very important, as hundreds of suspect fires are found nationwide. The case becomes scary and dangerous to members of the team, as well.
