Introvert Mikko is anxious that he won’t be able to come out of his shell during the weekend at his relatively new spouse’s cottage. His spouse Hanna is certain that Mikko will make a great first impression on her chosen family, the three friends that they are hosting. When it’s time for the sauna Mikko has not, despite all his attempts, figured out the sauna dress code of this new social bubble. As he steps into the sauna, Mikko realizes he’s the only one wearing swimwear—everybody else is naked. This traumatising event causes mixed emotions which Mikko is unable to shake away. Mikko tries to come out of his shell with his own way but everything ends up going even worse.
