With three years under their belt, the rookies of 15 Division know that rolling with the punches is more than just a life lesson, it's an essential part of the job. Change is the only constant, and if you don't adapt, you're left behind. Now, for these five officers, the time has come to look change right in the eye and make some big, bold choices.

Season five returns with two lives hanging in the balance. Officers Sam Swarek and Chloe Price have been shot in the line of duty and both are in critical care, but life at 15 Division must go on. But as the shell-shocked officers struggle to pull the pieces of their lives back together, they can't help but wonder -- will things ever work out the way they're supposed to? It's a season of life-altering decisions, and with Andy torn between Sam & Nick, she welcomes the professional distraction of training a challenging new rookie and will learn that sometimes even making the right choice can have serious consequences.

Last season the officers at 15 Division unearthed their sins of the past – dug through it, aired it out, and paved the way to move forward. They have all grown and are more resilient than ever. This season, they will have to learn to embrace living in the gray areas, because life is complicated and the best laid plans are just that. But sometimes it’s the unpredictable things life throws our way that turn out to be exactly what we need.
