In Charlotte, rookie homicide Det. Brian Whitworth is assigned his first case when a woman is discovered on her bedroom floor, stabbed to death. Hampered by false leads and a lack of eyewitnesses, Whitworth must rely on the physical evidence to bring... (more) the killer to justice. Meanwhile, in Louisville, Det. Jon Lesher investigates the homicide of a 43-year-old father, gunned down in front of his house for telling a rowdy group of men next door to quiet down. The case comes to a standstill when an eyewitness steadfastly upholds the street's code of silence. Lesher must use his veteran-interview techniques to break the code and get the witness to talk.
