Teachers Martin, Tommy, Peter, and Nikolaj are colleagues and friends who work at agymnasium school inCopenhagen. All four struggle with unmotivated students and feel that their lives have become boring and stale. Martin is confronted by his senior students and their parents, who express that he has become a barrier to their passing their history exams. At a dinner celebrating Nikolaj's 40th birthday, the group discusses a theory inspired by the work of psychiatristFinn Skårderud—that humans are born with ablood alcohol content (BAC) deficiency of 0.05% and that maintaining a BAC of 0.05% makes one more creative and relaxed.
The friends decide to embark on an experiment to test Skårderud's theory. They start a group log documenting their experiences as they drink at regular intervals to maintain this blood alcohol level. Two of them have personal struggles that make the experiment particularly appealing: Martin is depressed and alienated from his family and students, while Nikolaj's wife seems to have contempt for him. They agree on a set of rules: their BAC should never drop below 0.05 during the day on weekdays, and they should not drink after 8:00 p.m. or on weekends. Each man finds his own way to sneak alcohol during the day while teaching or coaching children, but they never drink and drive, with 0.05 being the legal limit.
Within a short period, all four find their work and private lives more enjoyable and successful. Martin, in particular, is delighted as he reconnects with his wife and children. His teaching becomes inspired, and his students begin enjoying class and respecting him. He even incorporates alcohol into his history lessons, engaging his heavy-drinking students. Encouraged by their success, the group decides to take the experiment further, increasing their BAC minimum to 0.10. Still feeling the benefits, they eventually push the boundaries further, deciding one night to drink to oblivion to test its liberating effects. However, after returning home incapacitated, both Martin and Nikolaj are confronted by their families. Martin's family expresses concern, revealing that they have known he has been drinking for weeks. He and his wife acknowledge their growing distance, and she admits to infidelity. The group abandons the experiment. Martin and his wife separate, and although he tries to make amends, she rejects him.
All members of the group stop drinking during the day, except for Tommy, whom the others try to support. However, at a faculty meeting where the headmaster reveals that teachers have been drinking at work, Tommy arrives visibly intoxicated. Later, he boards his boat while drunk, takes his old dog with him, motors out onto the bay, and ultimately goes overboard, drowning at sea.
After Tommy's funeral, the three remaining friends go out to dinner to celebrate his life, enjoying sparkling wine. While dining, Martin receives a text from his wife saying she misses him. As they sit by the harbour, recently graduated students pass by, celebrating in their customary drunken revelry. Martin, Peter, and Nikolaj join them in drinking and dancing. Martin, a former jazz ballet dancer, finally gives in to his colleagues' previous urgings and dances with the students. His movements grow increasingly energetic and joyous before he finishes his dance by spontaneously jumping into the sea.
The film was based on a play Vinterberg had written while working atBurgtheater, Vienna.[6] Additional inspiration came from Vinterberg's own daughter, Ida, who had told stories of the drinking culture within the Danish youth.[7] Ida had originally pressed Vinterberg to adapt the play into a movie, and she was slated to play the daughter of Martin (Mads Mikkelsen). The story was originally "A celebration of alcohol based on the thesis that world history would have been different without alcohol."[6] However, four days into filming, Ida was killed in a car accident. Following the tragedy, the script was reworked to become more life-affirming. "It should not just be about drinking. It was about being awakened to life," stated Vinterberg. Tobias Lindholm served as director in the week following the accident. The film was dedicated to Ida, and was partially filmed in her classroom with her classmates.[6]
During production, the four main actors and Vinterberg would meet to drink just enough to let go of embarrassment in front of one another. They would also watch drunk people onYouTube to better understand how completely inebriated people would act.[8]
