Four friends, all high school teachers at various stages of middle age, are stuck in a rut. Unable to share their passions either at school or at home, they embark on an audacious experiment: to see if a constant level of alcohol in their blood will help them find greater freedom and happiness.
There is an obscure philosophical theory that humans should have been born with a small amount of alcohol in our blood; that modest inebriation opens our minds to the world around us, diminishing problems and increasing creativity. Intrigued, Martin (Mads Mikkelsen) and three of his friends, all weary high school teachers, embark on a risky experiment to maintain a constant level of intoxication throughout the workday. Initial results are positive, but as the units are knocked back and stakes are raised, it becomes increasingly clear that some bold acts carry severe consequences.
