In 1989 a country boy doesn't want to eat potatoes at home. He wants to introduce something more exotic to his parents. One day he takes his savings and his moped to a pizzeria in town.

Middle-aged sisters Taina and Pirkko are famous for their Finnish farmhouse ale called “sahti”. The third sister, Päivi, is getting married, and she asks her sisters if they can make 100 liters of sahti for the wedding. Unfortunately, it’s too good not to drink it. The sisters wake up in a horrible hangover and realize they have drunk it all. They have 24 hours to find 100 liters of good sahti, or they will lose all the respect.
