Once the brightest teacher at his high school, Martin has fallen into a seemingly permanent funk. He’s barely present in his classes – the students and their parents even attempt an intervention – and his marriage is slowly dissolving. At a birthday celebration, his three closest colleagues (all men), cajole teetotaller Martin into boozing along with them. They get progressively drunker and the shit-disturber of the group, Nikolaj, tells them about an obscure philosopher who argued humans aren’t born with enough alcohol in their blood. As an “experiment,” he proposes they all drink constantly throughout the day to maintain the “proper” blood-alcohol level of 0.05%.
Initially, the boozing seems enormously beneficial. A reinvigorated Martin begins to engage with his students and shocks his long-suffering wife, Trine, with his new-found zest. But as the gang pushes their experiment further, issues that have been simmering for years come to the fore and the men are faced with a choice: reckon with their behaviour or continue on the same course.
