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 day
