The cops uncover a man with a secret second life as they try to learn who opened fire on a group of people disembarking from a party cruise, but his guilt or innocence becomes almost a second thought as Schiff goes toe to toe with the governor and the States Attorney General over the decision to seek the death penalty.
The cops' best hope of finding a kidnapped hired car driver alive is one of the armed robbers who grabbed him after a job, but the immunity deal he demands in return would effectively preclude his prosecution for the shooting death of an off-duty cop, placing McCoy in a difficult position as he seeks to placate the cops, who want the guy prosecuted, and the kidnapped man's wife, who wants every avenue of saving her husband explored.
Back in New York with their suspect, Briscoe and Curtis try to pin down his schedule on the night of the murder, but find instead that another man was in the area at the right time and more importantly, might have a motive for the crime. But after the issuance of a new arrest warrant, McCoy and Ross have to fly to LA to defend their warrant against attacks by the man's defense counsel, Ross's former husband Neal Gorton.
An unpromising case of murder suddenly develops new leads when the cops explore the possibility that the victim was mistaken for someone else. McCoy walks a thin line in the matter of ethical conduct as he tries to make a case against a lendor who uses unscrupulous methods to collect the money owed to him.
Curtis, angered by the attitude of an old colleague of Briscoe's, looks beyond the findings of an IAB investigation and turns up evidence of police corruption that puts the DA's office into competition with an ambitious judge and Briscoe under investigation for stealing evidence from a police lockup.
