"Brooklyn Nine-Nine" detectives Jake Peralta (Andy Samberg) and Rosa Diaz (Stephanie Beatriz) caught themselves in trouble again as "Brooklyn Nine-Nine" season 4 finale comes near. Jake and Rosa's misfortune continues as "Brooklyn Nine-Nine" season 4 is about to end with two back-to-back episodes.

"Brooklyn Nine-Nine" season 4's upcoming episodes depict the last cases for the Brooklyn Police Department. In investigating one of the cases, Jake and Rosa will encounter an unexpected bump on the road. This time, their reputation, integrity and freedom are on the line. 

According to Spoiler TV, the first-half of "Brooklyn Nine-Nine" season 4 finale's two back-to-back episodes bears the title "The Bank Job." It will feature a number of guest stars, namely Ryan Phillippe of "Shooter," Gina Gershon of "Showgirls," and Jason Mantzoukas of "The League."

Lieutenant Hawkins, played by guest star Gershon, together with Jake and Rosa, will be immersed in investigating a bank robbery. As the investigation proceeds at the crime scene, the detective duo will start to detect things that will make them suspicious of Hawkin's team. This will lead them to speculate that the latter are behind the robbery.

A secret will unfold, forcing the trio to call for back-up. The rescue team to arrive will include Ray Holt (Andre Braugher) and Pimento (guest star Jason Mantzoukas). On the other side, detective Charles Boyle will focus his attention on Gina Linetti's (Chelsea Peretti) new boyfriend (Phillippe).

Meanwhile, the second half of "Brooklyn Nine-Nine" season 4 finale is titled as "Crime & Punishment," and it will be an unlucky episode for Jake and Rosa as they will be framed for a crime they did not commit. Will they be able to prove their innocence before things get out of control? Is Hawkin's team responsible for the bank robbery? 

Fans would know the answer in "Brooklyn Nine-Nine" back-to-back season 4 finale episodes, which will air on Tuesday, May 23, at 8 p.m EDT on FOX.
