Wanda and Janek have been together "forever". However, after 10 years, their relationship resembles a charger cable that a dog has bitten - it still charges. After another argument, it is not really known what it was about, they make a decision - they go on a last-chance expedition. They buy a sled, load it with only the necessary things and set off along the shores of the winter Baltic Sea. From Międzyzdroje to Piaski. If they do not leave the beach and do not break the rules of travel - they will stay together forever, if they fail, they will never see each other again.
