Ep 1. Undercover

Detective Jake Peralta and the rest of the 99th precinct are back for more action-packed laughs in season 2 of Brooklyn Nine-Nine. In the premiere episode entitled "Undercover," Jake goes deep undercover to bring down a drug ring and stop a mass poisoning.

After a successful bust in the season 1 finale, Jake is feeling confident and eager for his next case. However, when Captain Holt assigns him to go undercover to investigate a drug ring operating out of a local club, Jake is less than thrilled. The reason for his reluctance is that going undercover means he has to leave behind his teammates, who he considers to be his second family.

Despite his reservations, Jake jumps into his new identity with enthusiasm. He creates a new persona as "Laminated Badge," a tough, leather-jacket-wearing drug dealer who has connections with the club's owner and can supply the highest quality of drugs. His plan is to get close to the drug ring and gather evidence to make an arrest.

As he spends more time in his new identity, Jake begins to enjoy his new persona and even starts to develop a friendship with the club owner's daughter, Sophia (guest star Eva Longoria). He starts to realize that this new identity is not just a job, but a way of life. He also starts to see how dangerous this new world can be, as he witnesses first-hand how the drug trade can ruin people's lives.

Meanwhile, back at the precinct, Jake's absence is felt by his friends, who are worried about him and also dealing with their own issues. Sergeant Terry Jeffords is struggling with the decision to take a desk job in order to be with his family, while Detective Rosa Diaz is trying to come to terms with her feelings for her new boyfriend.

As the investigation heats up, Jake finds himself in increasingly dangerous situations. He has to navigate the tricky world of drug dealers, informants, and corrupt cops. The stakes are raised when he discovers that the drug ring is planning a mass poisoning that could kill thousands of people.

The action-packed episode comes to a thrilling conclusion as Jake and the team race against the clock to stop the drug ring and prevent a catastrophic attack. The episode ends with a satisfying resolution to the case and a touching moment between Jake and his friends.

Overall, "Undercover" is a fantastic season premiere that delivers everything fans love about Brooklyn Nine-Nine: great humor, compelling characters, and exciting action. It showcases the strengths of the show, including fantastic writing and strong performances from the cast. It sets the stage for an exciting season 2 full of twists, turns, and hilarious hijinks.
