Dan's police interrogation techniques come back to burn him when it is ruled by the court that his interrogation of a drug smuggler was illegal. As a result, the felon busted by Jack and Dan months before is set free. Without access to any department resources, Dan vows to put away the entire drug smuggling ring with just his pocket money. Along the way, the partners find themselves trapped in a truck full of scented candles, Jack is reprimanded in front of his ex, and Jack and Dan get stuck in the middle of yet another shoot out.

Jack's former partner George Jenkins, who is now the department deputy chief, gets involved when Liz's informant against a member of the mafia is murdered and it is believed a corrupt cop was involved. Dan's former partner Frank Savage also aids in the investigation.
