Mads Mikkelsen, Thomas Bo Larsen, Magnus Millang, and Lars Ranthe star in director/co-writer Thomas Vinterberg's dramedy. Jaded with their lives as high school teachers in Copenhagen, four colleagues decide to test a psychiatrist's theory that having a constant blood alcohol content (BAC) of 0.5 will improve their quality of life. The experiment begins to take its toll when they decide to achieve a daily BAC of 1.0.
