Plot summary
AFC Richmond can win the Premier League on the final day of the season, as long as Manchester City lose or draw in their match. Richmond will face West Ham United, just as Rupert (Anthony Head) has become involved in a scandal, with Bex planning to divorce him over his "inappropriate relationship" with his former assistant Ms. Kakes.
Higgins (Jeremy Swift) informs Rebecca (Hannah Waddingham) that the club value is at an all-time high and suggests she sells 49% of her shares, which will leave her with majority ownership. However, Rebecca is thinking of selling the club entirely, since she feels she has nothing to prove now. She remarks that she took over ownership of the club only to ruin Rupert's life, but he seems to be doing a pretty good job of it himself. Roy (Brett Goldstein) feels that Jamie (Phil Dunster) is trying to resume his relationship with Keeley (Juno Temple) and asks him to step aside. Jamie refuses and reveals that her explicit video was made for him, which angers Roy. After fighting each other, they visit Keeley to make her choose between them. Insulted by their sexism, she chooses neither and kicks them out. They realize their mistake and leave to get some food.
Ted (Jason Sudeikis) and Beard (Brendan Hunt) announce they will return home at the end of the season. At the end of their last practice before the match against West Ham, the team surprise Ted and Beard by performing " So Long, Farewell ". Trent (James Lance) gives Ted and Beard a draft of his book, The Lasso Way, for feedback. Nate (Nick Mohammed) is back as assistant kit man, and is jokingly fined by the club for his season-long absence. Finally ready to talk with Ted about his departure, Rebecca reveals she is selling the club, explaining "if you go, I go". She begs him to stay, but he maintains his position. In the locker room, Nate tearfully apologizes to Ted, after noting that the "Believe" sign is no longer in the room.
The first half of the final match of the season ends with West Ham leading 2–0, while Manchester City is leading over Liverpool. At halftime, the Richmond players reveal they have kept the pieces of the ripped "Believe" sign, and reassemble them. During the second half, Jamie scores a goal, and later wins a penalty kick. Jamie offers the kick to Dani, who instead gives the penalty to Isaac (Kola Bokinni). Despite never having made a successful penalty kick before, Isaac ties the score by blasting right through the net into the stands.
Rupert furiously reprimands West Ham's manager, George Cartrick (Bill Fellows), telling him to take out Jamie by injuring him. When George refuses, Rupert assaults him. This prompts the crowd to jeer Rupert, and he leaves the stadium in disgrace. In the final minute, Richmond wins a free kick. Using a strategy developed by Nate, Sam (Toheeb Jimoh) scores the winning goal. Because Manchester City wins their match, Richmond finishes second overall, but Ted still receives widespread praise for the achievement.
At the airport, Ted says goodbye to Rebecca, who has chosen to sell 49% of Richmond to the fans while maintaining ownership. Before the plane takes off, Beard explains that he wants to stay in England to be with Jane, and the two share an emotional farewell before Beard fakes an appendicitis attack to get off the plane. As she leaves the airport, Rebecca runs into the stranger she met in Amsterdam (Matteo van der Grijn) with his daughter, and both smile at their surprise reunion.
Trent finds his draft with extensive notes from Beard. Ted's note says he loved it but suggests changing the title, saying "It's not about me. It never was"; so Trent changes it to The Richmond Way. Rupert is removed as owner of West Ham and is ostracized by the media. Roy becomes the new manager of Richmond. Sam is selected to play for the Nigeria national football team. Jamie reconnects with his father (Kieran O'Brien) and remains friends with Keeley and Roy. Keeley and Barbara (Katy Wix) reopen their PR firm and propose a Richmond women's team, which Rebecca gleefully agrees to.
Sharon (Sarah Niles) is hired as Richmond's Head of Mental Health, and Roy takes sessions with her. Nate glues the pieces of the "Believe" sign back together, and he, Roy, and Beard place the re-assembled "Believe" sign back in the locker room. Beard marries a now-pregnant Jane in a pagan ritual at Stonehenge, with the members of Richmond in attendance. Ted, now coach of Henry's soccer team, reminds his son to "be a goldfish", after missing a goal. As Henry goes back to play, Ted smiles, content.
