The show follows 10 contestants who compete to be the best cleaner in Denmark. Each week, the contestants are given a different cleaning challenge, such as cleaning a festival toilet, removing limescale from a bathroom, or cleaning up after a dog. The contestants are judged on their speed, thoroughness, and creativity. The winner of each challenge receives a point, and the contestant with the most points at the end of the season wins the grand prize of "Den Gyldne Rengøringsspand" (The Golden Cleaning Bucket).
The series takes place after 2014 in a de-occupied mining town that is gradually returning to peaceful life. The main characters are two families that have long been separated by quarrels and endless arguments. The misunderstanding between them does not subside even after the news of their children's engagement. To make matters worse, former friends and now sworn enemies Pavel Dotsenko and Grisha Kulikov become the main contenders for the mayor's office. The competition for the favor of the townspeople constantly leads to complicated, confusing, and sometimes funny situations. Will the enemies be able to unite on the verge of a full-scale invasion by Russia, or will they be able to become one family for the sake of the future?
