A woman and a man walk down a beach dragging a sled filled with luggage looking like polar explorers. After another row and an attempt to divorce, Janek and his wife give themselves an ultimatum and decide to go on a 400-kilometer hike along the Baltic Sea in the middle of winter. If they can overcome the challenge, they will stay together forever, if not, they will break up. During their journey, they must overcome bad weather conditions and once again learn how to be together.
