Old-school cop Dan Stark and modern-day detective Jack Bailey expose the big picture of small crime. Pursuing a routine investigation of a stolen humidifier, Jack and Dan are inadvertently thrust into a much larger case involving drug smugglers, hired assassins and a stolen green golf bag. Reminded of the way he busted punks back in the good old days, Dan convinces Jack to go along for the ride, and in their reckless pursuit of justice, the two wind up risking their lives, breaking a flurry of department regulations and reminding their boss, Lieutenant Ana Ruiz, and Jack's ex-girlfriend, Assistant District Attorney Liz Traynor, why these good guys will be spending many more days investigating seemingly minor crimes.

While investigating a vandalism case, Jack and Dan discover a pattern of stolen vintage cars around the city. Unable to set up a sting operation using a department "bait car," Jack and Dan must go on their own to pursue the elusive car thieves.

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.
