As Detectives Briscoe and Curtis investigate the death of an audio installation salesman, their search introduces them to a web of players who are all linked to the murderer, and consequently, the mafia. When Assistant DA's McCoy and Carmichael go to work, they face a remorseless suspect who has plenty of 'friends' who will give anything to keep him out of prison. To build a strong case against the suspect, McCoy and Carmichael face the challenge of convincing witnesses to testify and ensuring their safety. Later, District Attorney Schiff is forced to step in to adjust McCoy's ideas of proper punishment for the accused.
