Brooklyn Nine-Nine Wiki

"Blue Flu" is the 3rd episode of Season Eight of the NBC television show Brooklyn Nine-Nine.[1]

Episode Synopsis[]

Capt. Holt and Amy manage an understaffed precinct. Jake and Charles investigate.[1]


O'Sullivan (John C. McGinley) engineers a walkout of uniformed officers by claiming illness in response to an alleged anti-cop incident involving a mouse found in a burrito. Willing to investigate further and force the officers to return to work, Holt (Andre Braugher) orders the squad to investigate the incident.

Noticing that the officers report suffering infectious mononucleosis, Jake (Andy Samberg) decides to use Boyle (Joe Lo Truglio) to go to the doctor and get the diagnosis to prove the other officials are faking the reports. But Boyle's visit to the doctor soon turns concerning when the doctor notices a worrying sign on Boyle's testicles, which could be testicular cancer. Waiting for the test results causes Boyle to worry in the precinct. During a stakeout, he confesses to Jake that he fears dying as he won't see Nikolaj grow and miss more adventures with Jake, moving Jake to tears. Meanwhile, Holt and Amy (Melissa Fumero) asks other precincts for help in their under-staffed precinct. However, the precincts send their own "Hitchcocks and Scullys". In order to motivate them, Amy gives them pedometers, promising one week of overtime to whoever has the most steps.

Terry (Terry Crews) struggles to work due to a stomach bug and goes home. Holt asks Rosa (Stephanie Beatriz) for help and she provides information revealing that the officer planted the mouse in the burrito in exchange for a photo of Holt's tattoo. Holt shows it to O'Sullivan but he twists the situation into another to avoid calling off the Blue Flu. Terry manages to infiltrate the union and records the officers confessing to the deception. However, his stomach bug overshadows the recording and they lose evidence. To worsen the situation, Amy finds that the "Hitchcocks and Scullys" use massage chairs to increase their pedometers.

After getting the test results, Jake and Boyle celebrate as his condition is not lethal. They turn the report to O'Sullivan, proving that the other officers aren't sick. O'Sullivan accepts faking it but says the officers are still sick because they were exposed by Terry's visit. A defeated Holt goes to the bar where Boyle gives him a talk about his fears. Holt then gets an idea. He confronts O'Sullivan at his office, proving that with fewer officers, the 99th precinct hit fewer complaints and bad records. O'Sullivan is forced to end the Blue Flu or having the officers fired for missing work. As Holt addresses the precinct, Jake uses the opportunity to show Holt's tattoo (having paid $2,000 to Rosa for the photo) but the precinct is disappointed when it's just a decimal point. It is revealed that the photo is fake and the episode ends before Rosa says what the tattoo is.
