This romantic comedy follows the life and times of an urban, bilingual, progressive couple in their thirties: Aino from Finnish Lapland, and Swedish-speaking Micke. They are forced to move to an upper-class neighborhood in Helsinki, into an apartment owned by Micke's wealthy parents, who also live next door.
Aino is invited to the first crayfish party of her life at the home of her parents-in-law Lasse and Gunilla. A surprise visit from Aino's relatives falls on the same day. Whose relatives are more tiresome?
