A single-camera ensemble comedy following the lives of an eclectic group of detectives in a New York precinct, including one slacker who is forced to shape up when he gets a new boss.
A detective from Special Crimes, takes over Jake’s nearly solved murder case and steals his thunder. Over a few drinks, Jake enlists the precinct to get revenge and find the murder weapon before “The Vulture” does. Across town, Captain Holt and Gina help Terry get re-certified to carry a gun.
Much to the team’s annoyance, Jake hits on an attractive medical examiner, Dr. Rossi at a crime scene and holds up the autopsy report. He learns his lesson when Dr. Rossi turns out to be more than he bargained for. Meanwhile, Amy’s purse-snatching case is stalled when the sketch artist is out sick, but she discovers that Sgt. Jeffords has hidden artistic talents.
Jake has a slew of unsolved cases that he can’t seem to close, and the other detectives don’t want his losing streak to rub off on them. Meanwhile, Holt asks Amy to run lead on the Junior Policeman Program for at-risk youth, and she enlists Rosa and Gina’s help. Also, Boyle helps Sergeant Jeffords with a special case he cannot solve.
When Jake is late for roll call, Captain Ray Holt assigns him to a graffiti case that Jake feels is below his level. However, when the culprit turns out to be the Deputy Commissioner’s son, the case becomes a major problem. Meanwhile, Gina’s psychic friend visits the precinct and gets inside Charles.
Detective Jake Peralta is a talented, but carefree police detective at Brooklyn's 99th precinct who, along with his eclectic group of colleagues, are used to having a lax captain around the office. However, when tightly-wound Captain Ray Holt takes over, he is determined to make this dysfunctional group of detectives into the best precinct in Brooklyn.
