It's New Year's Day, 2014. Joshua Rothchild, a young NYPD sergeant, and his officers respond to the city's first homicide of the year. The victim is a middle-aged ex-con, found riddled with bullets in a hallway. After an embarrassing mishap at the crime scene, Josh is soon bitten during a violent encounter with a suspect. He was already considering a career change, and recent events are pushing him to leave policing for good.
Amid the flurry of police activity in their Brooklyn precinct, no one gives much thought to the New Year's Day homicide. But as the weeks go by, a dogged detective named Espinoza continues to investigate a murder that everyone else has forgotten.
As a series of violent events unfolds, Josh begins to question his detachment and decides to help Espinoza with the murder investigation. But often the biggest danger to cops comes from within the shadowy labyrinth of the NYPD, such as higher-ups who are more concerned about their precinct's statistical performance than justice for the victims.
Will Josh be able to leave a job he once loved with his head held high, or will he be crushed by the grinding gears of the department? If he really wants to help solve the murder, he'll have to put aside his preconceptions and dodge the bullets coming at him from all sides.
