Jake: Excuse me. Uh, so earlier at Amy's, I didn't give a real toast because I didn't know what to say. But since that time, a wise unsmiling man named Jerald Jimes made me realize what I am thankful for. So, I'd just like to say I am happy to be here with my family. My super weird family with two black dads, and two Latina daughters, and two white sons, and ... Gina. And I don't know what you (Scully) are. Some strange giant baby? To the Nine-Nine!
Amy: Rosa is even wearing her formal leather jacket.
Rosa: It's the one without any blood on it.
Gina: Oh, my God, Amy, that's so cool that you still live with your Grandmother.
Amy: I live alone. This is my stuff. I like quilts.
Gina: Stop. Each sentence is getting sadder.
Amy: Hitchcock, why do you have your shirt off?
Hitchcock: Can't spill food on your shirt if you're not wearing one.
Terry: Okay. Excuse me. Can we please eat? My body is starting to digest itself. Terry needs nutrients!
When Boyle arrives at work, the rest of the squad are playing "Boyle Bingo: Thanksgiving Edition". Everyone filled out their card with possible Charles-related scenarios for the holiday, and the first to bingo wins $100.
When Jake returns to the precinct after a drugs bust, Amy tells him to go home and get dressed for her Thanksgiving dinner. Jake is not a fan of Thanksgiving or dressing up for the occasion. Nevertheless, Amy tells him he will be giving a toast which he should go prepare. Meanwhile, Terry is angry that Boyle left the fridge door open. All the food that Terry's wife prepare for him before she went out of town is ruined. When the Sarge sees Scully, he demands access to Scully's secret stash of food.
Amy goes to Captain Holt's office to check whether he will be attending her Thanksgiving party. Since Raymond's husband is out of town for work, he agrees to attend Amy's dinner. Outside the Captain's office, Gina wonders why Amy is so excited. After Amy explains the Captain will be coming to her party, Gina is disappointed that impressing Holt is the reason behind Amy hosting a dinner.
Jake find Captain Holt in the break room, finishing a call with his mother whom he refers to as "Your honor". Jake wants a new case from Holt, but he says all open cases are assigned. The Captain realizes Jake is trying to get out Amy's Thanksgiving dinner. Jake admits he would rather do what he does every year, sit at home, watch football and eat "mayo nut spoonsies." Captain Holt says if a case opens up, it's Jake, but otherwise he will be at Santiago's dinner as a professional courtesy.
The squad excluding Captain Holt gather at Amy's apartment for her Thanksgiving dinner party. Terry is very hungry and desperate to eat, but Amy won't let anybody eat until Captain Holt arrives. After Captain Holt arrives, Amy starts to give her toast. Captain Holt's phone rings, interrupting Amy's speech. When the Captain explains he has to go back to the station as somebody stole $10,000 from the evidence lock-up, Jake is excited that he now has a case to jump on.
At the precinct, Captain Holt and Jake watch the security tapes from the evidence lock-up to see what happened to be the missing $10,000. On the footage, they see a guy enter the evidence lock-up and take the money. They decide to check all the perps that were released from holiday earlier in the day. Back at Amy's apartment, Boyle gives an awkward speech. Terry can't take it any more and starts eating the potatoes, but immediately stops in disgust. Amy admits she used baking soda instead of salt.
Captain Holt and Jake get in a squad car to go check on two recently released perps that match the build of the guy on the security tape. Jake noticed the guy on the footage was left-handed, so they'll give the suspects a made-up form to sign and see which hand they use.
Back at Amy's apartment, Terry claims to be stuffed. Scully emerges from the bathroom, saying the toilet is overflowing. The rest of the squad admit to getting rid of their food down the toilet. With her meal a disaster, Amy says Thanksgiving is over and tells everyone to go home. Charles suggests they all go to a bar to get some food.
Outside a suspect's house, Jake tells the Captain they should do the whole thing in character. Jake says he'll play Detective Bart Barley, a tightly wound guy who hates violence against animals. Holt will be Gerald Jimes, a man who solved every crime but one, the murder of his wife by a man in a yellow sweater. Captain Holt tells Jake to take this seriously. The first suspect signs the form with his right-hand.
At the next suspect's house, Jake still wants to be Barley and Gimes. When they enter the suspect's family home, the whole family breaks out in an argument. To get things under control, Captain Holt yells about the murder of his wife by a man in yellow sweater. After the guy signs the form, Jake says they caught their man. Captain Holt is confused as the man signed the form with his right-hand. Jake points out his brother was throwing bread rolls with his left hand, and his hoodie matches their security footage. When they ask where the money is, the guy admits he bet it on all a football game and it's with his bookie. Jake is excited that the case continues as they go to a Chinese betting parlor.
At a bar, the bartender says the cook's gone home. When a desperate Terry eats all the pretzels, the bartender agrees to call the cook back in. Amy is sad at how the night panned out, saying she just wants Holt to pay attention to her like he does Peralta. Amy says she can act out too, and to demonstrate she throws a glass towards the bar. After Amy's shot breaks a shelf of expensive liquors, the gang are kicked out of the bar. Meanwhile, Jake and Captain Holt play at the betting palor.
After the rest of the squad return to the precinct, Scully reveals his secret food stash, but unfortunately rats have already found it. When Amy calls it a night, Boyle asks for one hour to turn Thanskgiving around. Elsewhere, Captain Holt and Jake enter an illegal backroom. Jake is more concerned with learning the score of the football game, than the numerous illegal activities going on in the room.
After their successful raid, Captain Holt says they should return to Santiago's party. When Jake says no, Captain Holt wonders what Jake's problem with celebrating the holiday is. Jake explains the holiday sucked because his mom worke and his dad was gone. He just sat at home watching football, which is what he'd prefer to do now. Captain Holt says that he came from a very formal family, but the beauty of being an adult is you can make a new family with new traditions. Jake doesn't realize the squad is his new family.
After Captain Holt returns to the precinct, Boyle shows up with lots of take-out delivery guys. Boyle asks for fifteen minutes to serve up their multi-ethnic, non-traditional Thanksgiving. Amy goes to tell Captain Holt how she feels about him, but he has already read her toast after Gina gave it to him. Amy is happy to hear the Captain's comments.
As Boyle presents the take-out Thanksgiving dinner, Jake arrives dressed up in a suit. A starving Terry dives right into the food. Amy thanks Gina for showing her toast to the Captain, though Gina insists she did it as a prank. Rosa tells Boyle this is the best Thanksgiving meal. Jake leads a toast to his super-weird family in the precinct.
