Plot
In 1988, Paul Ashworth is an English teacher where new history teacher Sarah Hughes has just started. From the first day of class they clash. His classroom is lively and boisterous, chanting for Arsenal F.C. which she says distracts her students.
Sarah complains about him to her flatmate Jo, who jokingly says they'll end up shagging. Paul talks about her to his friend Steve, saying that although she's pretty, they mutually hate one another. Steve suggests it is a promising sign.
In flashbacks, we watch Paul as a child as his dad, who he only sees sporadically as his parents are divorced, tries to connect with his children. Initially uninterested, when he is taken to a match, he loves the whole rowdy, lively experience.
In the present, Robert from the school team Paul coaches asks him to take him to a match, which he says no, sorry he can't. Discussing him with his mother, she is concerned. Paul says that, although he has poor penmanship, he's doing fine in his class. He suggests she take him to the next match as she's separated from his dad, to cheer him up.
After Parents Day, Paul offers Sarah a lift home as it's raining. She complains that, although she'd prepared, the parents preferred talking to him over her. Sarah invites him up and, as Jo isn't home, they sleep together, beginning a relationship.
When they've been together over 6 months, Sarah suggests they plan a trip somewhere. She offers to write suggested dates into his diary, but Paul is reluctant as he doesn’t have the next season’s football fixture list yet. Sarah remarks that indicates that he isn’t sure he’ll be with her in the future, but knows he’ll be supporting Arsenal. He counters that it’s no different to her knowing she’ll see her sister next season. Sarah points out that sisters ‘don’t have seasons’.
Nevertheless, Sarah finds herself influenced by Paul and gradually drawn into an interest in football, and so she goes with him to see an Arsenal match. The shoving and fanaticism she experiences makes her nervous. When it's discovered that over 70 fans were crushed to death at another match that same night, Sarah's incredulous that it doesn't dissuade Paul from attending matches in future.
Sarah then discovers she's pregnant and is unsure of what she wants to do. Paul is enthusiastic and declares they'll have to marry and have it, but she fears he wouldn't be available for the long haul.
Paul was offered the position of Head of Year, which he wasn’t initially interested in, as it would be more work for more money that he didn’t need. But now facing the prospect of increased obligations, he approaches the headmaster, saying he has changed his mind about the promotion. He is pleased until Paul tells him why, about being with Sarah and the upcoming baby, which the headmaster considers sets a bad example to pupils.
The same day Paul interviews for the job, for which they turn him down, Arsenal loses an important game, worsening their chances to win the championship. Sarah comes over to offer sympathy over the interview, but the Arsenal loss is what is upsetting him. She says ‘it’s only a game’ which makes Paul very angry, as he has never cared about anything more. They argue and she leaves, their relationship seemingly over.
The school's big football championship final comes. Robert misses a penalty kick and the match. Paul asks him if he had the choice between success in this match or a positive outcome of the Arsenal-Liverpool league championship contest, what would he decide; his answer is the latter. So Paul suggests he focus on the bigger game, consoling him by humorously suggesting he had ‘done his bit’ by missing a penalty.
Just before the match that will decide the League Championship in Liverpool, Sarah checks in with Paul. Unsure if she'll be able to see it, she wishes them luck, knowing the team must win by 2 goals. He reveals that he has resigned from his teaching post, as he needs to seek better pay elsewhere and considers it untenable that they remain colleagues with him the estranged father of her child.
Everyone who's watching the match on TV is all nerved up. Paul complains to Steve that it is too depressing to watch as Arsenal are sure to fail, and suggests he will leave the flat, but then can’t tear himself away.
Even Sarah discovers the team is one-nil up in the last half, sneaking a look while at a house party with her students. She leaves and grabs a taxi to Paul's arriving at his door with one minute of the match remaining. Sarah's buzzing up at such an inopportune moment earns her a myriad of profanity out the window, as Paul shouts out that the interruption comes at the worst occasion of his life.
Suddenly realising it could be Sarah, Paul runs down to catch her, but she's gone. Hurrying back upstairs, he just manages to see the winning goal scored in the final moments of the match. It being the first time the club had won a championship after an 18-year-drought, the city comes alive with celebrations, as excited Arsenal fans pour into the streets. The initially saddened Sarah gets swept away by the wave of supporters. Meanwhile, Paul and Steve also celebrate, Paul now trying to assure Steve that he never lost faith that Arsenal would win.
Paul and Sarah find each other in the street amongst the crowds and kiss, instantly rekindling their relationship. From then on, he moves on with his life with her. Paul states that his happiness is no longer dependent on Arsenal.
