In the wake of the storm, NOPD officer Marlin Boulet attempts to rescue survivors, while his partner, Charlie Pratt, gets scared and takes off.Two years later.Captain Embry introduces Boulet to his new partner… Trevor Cobb, an ex-Army Ranger who did two years special ops in Afghanistan. Boulet can’t figure out why a guy from up north would want to be a cop in New Orleans.When Embry announces to the team that they need a couple guys to cover a charity event in the French Quarter to benefit the Ninth Ward, Cobb smirks. He thought this was the badass squad, didn’t expect to be covering social events. Boulet tells Embry that he and Cobb will take the assignment.That night at the benefit, Boulet toasts to a long partnership; but Cobb tells him he doesn’t drink on the job. An attractive blonde, Christina DuBois, hosts the event. She gets up and gives a pep talk about rebuilding the ninth ward. Boulet notices Cobb staring at her and informs him that she’s Rex DuBois’ daughter. He owns the casino. Cobb’s going to need to make a lot more than 29K a year to pluck that flower. Suddenly a shot rings out and Boulet’s friend and neighbor, Kaja Fontaine, the singer at the event, goes down. Boulet and Cobb jump into their car and pursue the shooter. Cobb shouts directions to Boulet as they track the perp through the city to the casino, where they find his car flipped and abandoned.One of the officers, Jeff “Glue Boy” Gooden, hands Boulet a baggie full of worms found in Kaja’s dressing room. Apparently they were delivered in a flower box. Boulet thinks he knows who sent them. Tommy Corville, a fisherman who was also Kaja’s boyfriend until she broke up with him a week earlier. Another officer, Ginger “Love Tap” LeBeau, informs Boulet that Kaja just died.Out on Tommy’s fishing boat, Boulet dumps the bag of worms on Tommy’s head while dangling him overboard. Tommy swears he’s been on the gulf coast shrimping for the past two days and had his brother deliver the worms. When he can’t give Boulet the name of any buyer, Boulet cleats the rope and Tommy plunges underwater. Cobb thinks maybe he’s going a bit “overboard,” but Boulet recounts other stories of Tommy’s abuse towards Kaja.Back at the station, Embry announces he’s sending some guys to the fish market to check out Tommy’s story. Ginger informs him that they found a couple joints and a gram of coke in Kaja’s car. Boulet insists she was off drugs; but in any case she wasn’t killed for them. Embry gives Boulet and Cobb the good news that they’ll be going back to the charity event for a second tour of duty… only this time they’ll be accompanied by a bunch of harbor cops. After the briefing, Boulet looks up and sees his old partner standing outside the fence.Charlie seems to know as much about the previous night’s event as Boulet does. He explains that he held onto his police radio when he left and he’s been diligently listening to it ever since. Charlie asks why Boulet hasn’t returned any of his calls. Mostly he wants to know if he’s talked to Embry for him yet. Boulet tells him he hasn’t and he’s not going to.Boulet comes home to find his estranged wife Ayana and their daughter Tawni. Ayana informs Boulet that they’re just back to get the things he refused to send them. Couldn’t bring himself to send them, he corrects her.At the charity event, Christina DuBois tells a reporter that she thinks Kaja would have wanted them to come back tonight… to reverse the perception that the city she loved is a lawless, dying place. The reporter thinks it’s remarkable that Christina can stay so positive given the tragic circumstances of her own brother’s death. Christina refuses to comment on that.At the bar, Cobb overhears Christina and asks Boulet what happened to her brother. Turns out he was murdered in the Ninth four years earlier. He stopped to change a tire and someone stole his wallet and bashed in his head. Boulet’s cell goes off. Tommy’s alibi checks out. He didn’t kill Kaja. Suddenly the party is engulfed in gunfire. Boulet and Cobb run out to their car as it explodes.The next day Ginger informs the team that in spite of all the gunfire, they somehow came out of it with only three broken bones. No fatalities. Cobb points out that the bullet holes in the banners were well above people’s heads. These guys weren’t shooting to kill… they were shooting to miss.In the casino security booth, Boulet and Cobb look at surveillance footage. No sign of their guy. Then Boulet notices a screen of gamblers with just part of a roulette wheel spinning in the corner. He asks the head of security, Gordon Wix, to show him the footage from Tuesday… at around 10:30pm when the shooter would’ve come through. Wix hesitantly nods to the technician who presses some buttons and the footage appears. Boulet notes that now the roulette wheel isn’t in the footage at all. Cobb asks what it would mean if all the sector’s cameras were off by a few inches. The tech responds that a four foot wide path would’ve been completely obscured. Wix turns to the room, demands answers. Then he promises to get to the bottom of it.Outside, Boulet notes that mistakes like that just don’t happen in casinos.Down the street, they run into Charlie, who’s been waiting for Boulet. He managed to come up with a file on the casino employees they just questioned. Turns out they are gulf war vets turned mercenaries. They’re part of BlackRiver Security and they’ve got a contract with the casino now. Boulet tells Charlie he did good. Charlie insists that he’s going to win back Boulet’s trust.Boulet and Cobb head to the DuBois estate where they inform Christina and her father about their suspicions. Rex tells them he’s not going to spy on his own employees. No problem, they’ll just get a warrant. They ask Rex if he’s really willing to take the risk that his daughter won’t be the next victim. He’s not. He tells them to do what they need to do… quietly.Boulet and his wife are sharing an intimate moment when they suddenly notice water pouring down the stairs. Boulet runs upstairs and grabs their terrorized daughter. Outside, Ayana starts screaming when she notices her address in Atlanta spray-painted on the side of the house. Whoever did this knows where she lives.Back at the Casino, Boulet, Cobb and the team make their arrests… and not quietly. At the station, Boulet and Cobb question Wix. He claims to have been at home in his hot tub at 9:15 the previous night when the water bomb incident occurred. Boulet tells him he thinks they figured NOPD cops were quitters, so they sent him a message. Then he makes it clear that they sent the message to the wrong guy.Back at the station, Embry reprimands Boulet and the team for their impulsive roundup at the casino. He’s already received two calls from the FBI because Black River Security is employed by the federal government. And more importantly, they give millions in campaign contributions to a particular political party. Get the picture? Embry sends them all off to gather some actual evidence.Boulet throws the keys at Cobb and instructs him to drive to Ziggy’s, his favorite gumbo joint. It’s what Boulet does when he needs to think. Under the freeway overpass, he tells Cobb to stop the car. They get out and Boulet jumps him. What the hell? Boulet wants to know who he really is. Man from Cincinnati driving to Ziggy’s and asking no directions. Boulet pulls a gun on Cobb and tells him if he lies again, he’ll cuff him before he even sees his hands. Cobb explains that he did his basic training at Fort Poke in Leesville and came down here all the time. Then he warns him that if he ever does that again, one of them isn’t walking away. Boulet drops the gun.Boulet looks down his street and for the first time notices all the “Sold” signs. He suddenly realizes that all the property in the ninth is being bought up by a single company called ‘Orleans Renewal, Inc. He pays a vis
