It's Helge Klingenfeldt's much-anticipated sixtieth birthday party, but no one is ready for the bombshell about to be delivered by his oldest son, Christian—a dark family secret that contributed to his twin sister's recent suicide. Helge Klingenfeldt (Henning Moritzen) is a respected Danish patriarch whose country estate is the scene of a grand celebration. Friends and relatives have arrived. The staff has prepared the most succulent foods to be served with the finest wines. Even Helge's squabbling adult children seem to be on their best behavior: free-spirited Helene (Paprika Steen), hot-blooded Michael (Thomas Bo Larsen), and sensitive Christian (Ulrich Thomsen) whose birthday toast turns the genteel celebration into a surprise party from hell.
