Snake Killer

The disturbance patrol officer Smiley returns to a reformed police department after the charges against him in a shooting case are dropped. The new unit will be run tightly, and any major investigation will be passed further up the system. But when Smiley gets a lead on an infamous kingpin known only as "The Viper", he decides to start his own investigation.

When Lea is found murdered, Smiley begins a hunt for the people responsible. The clues lead to Player's Club, where he finds the Viper's drugs and begins a relationship with Camilla. Louise tries to gain the respect of her fellow officers, who put her in harm's way to force her out. At her weakest, she's approached by Lisa Dahlin from the Public Prosecutor's Office to help bring down Smiley.

Disturbance Patrol's hunt for the Viper is hampered by Kourosh's arrest. But once they get a tapped phone on him, it leads them to Edmond, who proves a capable opponent. Louise's nocturnal investigation into the jet set's coke consumption leads her to Edmond's little brother. Smiley's investigation is uncovered and shut down, but when Niller kills himself in front of him, he refuses to let go.

Disturbance Patrol is torn by fear after the robbery. Khaleghi threatens their families, while Dahlin tries to have them suspended. Smiley is about to give in when Louise discovers a connection between their two cases. They intercept Khaleghi's next shipment where Smiley then kills Edmond. Smiley lets Camilla go and is recruited to a new reckless police unit. The Khaleghi family swears revenge.
