On the 10th anniversary of Hurricane Katrina everyone in New Orleans and on the Nightwatch recall their experiences with the storm and reflect upon the significance it still holds in their lives. Amid the remembrances, the city still needs its first responders. Over the course of a busy run of calls for EMT's, the police SWAT team looks to execute a high risk raid. The people on Nightwatch will do anything to protect their city.

Working together for years has turned Titus and Dan into great friends. On their shift, they come across people who are the victims of crimes perpetuated by those close to them. On calls like these, when they become more than just emergency medical technicians, they are counselors and therapists. They will do everything possible to steer some troubled people in the right direction.

Every night, the members of the Nightwatch are reminded in new ways to be thankful for what they have. Titus and Dan resuscitate an overdosing drug user just before all hope is lost. Brooke and Landon tend to a young girl with congenial heart failure. Later, a team of firefighters contain a fire before it can wreck havoc. Things get a little bit lighter when Titus and Dan learn that a familiar patient is also a secret admirer of Holly.

The brother of a paramedic gets sucker-punched; best friends get into an accident; one of the newest members of the Nightwatch comforts a suicidal patient, then reflects on the bonds he has forged during his first year in New Orleans

The New Orleans EMTs receive calls from every direction, from gunshot victims to seizures to a moped rider playing Pokemon Go.

Officers Roni and Cooper engage in a foot chase following a stabbing at a nightclub; Fire Rescue's Doug and Stokes try to save the life of a man shot in the throat; the hunt for a carjacker leads Will and Dimitri to the roof of an apartment complex.

Not all tragedies are created equal and tonight, when the men and women of New Orleans get word that one of their own has been seriously injured, they all reflect on the risks they take. Other calls during the night mirror that reality.

Titus and Dan race to save an 18-year old shot in the head through and through. Randy & his partner Devin, search for suspects in an armed robbery, which leads to a high-speed chase.

For the men and women on the Nightwatch, two things never stop: the calls and questions. How can someone shoot an eight year old boy? How do you stop the drug epidemic in the worst parts of New Orleans? How do you get guns off the street? As the first responders do everything they can do to save the victims of several shootings, a drug overdose and more; the police officers chase suspects who end up having illegal firearms. They all find themselves asking these questions and only wishing they had the answers.
