Last season was a rollercoaster ride and after all of the chaos and struggle, everyone's life was put in mortal danger. Chloe got shot in the neck and Sam intercepted a bullet meant for Nick and got shot in the chest. This season, the gunshots are still ringing in their ears, but life at 15 Division must go on. As the shell-shocked officers struggle to pick up the pieces, Andy and Sam find their way back to each other and she's tasked with training a challenging new rookie, under the watchful eye of a tough inspector. Although the officers have learned that life doesn't always have a fairy-tale ending, they're still holding onto hope that there will be a happily ever after.
