S3, E12: With the senior officers off on another assignment, the rookies of 15 Division are on their own. But a seemingly innocuous shift leads to a frenzied night in the station when an improperly searched prisoner pulls a gun on Chris in cells. With Internal Affairs looking for someone to blame and potentially fire, the rookies find themselves recalling and defending their actions during the chaotic shift. Knowing someoneʼs career may be on the line, they walk the delicate line between telling the truth and having each otherʼs backs as they reflect on the personal and professional choices that might have helped lead to the nights events. Meanwhile, Gail is still trying to be normal after her harrowing abduction; Chris is blindsided with a personal revelation; and Andy learns a dark secret about Nickʼs past. When the Internal Affairs inquiry reaches its end, it seems as though Chris will take the blame. But as another officer steps in and takes the fall, it becomes clear that 15 Division will actually be losing one of its rookies.
