Da Vinci's City Hall

Da Vinci starts his term as mayor with two homicides waiting to be handled -- an apparent gay-bashing death in Stanley Park, and the shooting death of a mental patient. Da Vinci has his hands full trying to deal with a number of squatters that Jacobs is trying to roust, then learns that Lloyd Manning, a new friend who was preparing to buy the racetrack, has lost an advertising deal because of a leak at City Hall. Meanwhile, Angie and Joe investigate the police-shooting death of a mental patient.

Zack continues to infiltrate the squatters, and learns of their new plans to make a stand against the city. Da Vinci continues his quest to get slot machines installed at the tracks and elicits the help of the city council worker believed to have blown Manning's ad contract. Mick proves that the bones of two young boys belonged to two missing aboriginal boys believed to have been in the sex trade.

Leary gets more information on the paedophilia ring, and learns that his key witness was a member of the ring. Jacobs is furious when he catches wind of Da Vinci's plan to institute a red light zone, and he and Klotchko partner up to bring the mayor down. Finn and Kosmo investigate two linked shootings -- that of a schoolteacher, and then that of an Indo gang member close by. Ferris gets herself on the wrong side of the firemen after they unknowingly interfere in a grow-op bust. Da Vinci spends the night at Billie Simms' party, not realising that Zack is trying to contact him regarding the raid on the squatters.

Da Vinci is pleased to learn that a fire captain, Roy Komori, has been rousting grow-ops by giving out fire inspection notices and wants to implement the idea across the board, but Jacobs again goes behind his back to sabotage his efforts. Leary follows the paedophile ring's trail to a radio host who has since passed on, but his daughter has some valuable information for him. The red zone seems to be working until the wrong person hears some confidential information. Kosmo and Finn wonder if the victim of the drive-by shootings was a case of mistaken identity.

Constable Tremaine dies in the grow-op bust because the cops were trying to bust down a door that opens out and things go from bad to worse when Jan Ferris tells her lawyer that she saw a fire inspection notice at the grow-op that tipped off the sitter to the upcoming raid. Meanwhile, thanks to Klotchko's continuing manipulations on Jacobs' behalf, Da Vinci faces opposition from both the city and the firefighters on the new cross-training plan; Leary gets a lead in the paedophile ring when Clarke Messner points the finger at Dubreau, a hotel owner they were looking at.

Da Vinci finds himself in the middle of a union war. Meanwhile, Leary continues investigating the paedophile ring, and when he comes up with a familiar name, takes it to Kosmo and Finn.
