The Drakenhjelm family has lived in the Rautakylä manor for over 150 years. The current master of the house, elderly baron Magnus (Adolf Lindfors), has been living for a long time in an unregistered relationship with his housekeeper Lisette (Naimi Kari), with whom he also has a son, Sebastian (Axel Slangus). After the baron falls gravely ill Lisette starts getting worried about losing everything, so with Sebastian on her side she demands the baron to write a letter to the pastor and ask him to come over to perform a wedding ceremony. Right after Sebastian has left to fetch the pastor, a threesome seeking shelter from the storm comes to the manor and wreaks havoc on the marriage plans..
