A 15 year-old boy is shot to death on a neighborhood street. Investigators Tom Cassidy and C.J. Dominic interview a witness who saw two unknown men attack and shoot the boy. Surveillance video from a nearby shop confirms the witness' story but doesn't give a clear picture of the attackers. Investigators are at a dead end - until they learn their witness really may know who the shooter is and was just too frightened to say. Cassidy and Dominic must find the witness and see if she can identify the shooter before someone else gets hurt.
