Would-be bride and groom Weronika and Łukasz decide to give themselves a second chance and invite their family to the wedding and reception in a seaside town. Among the invited guests are Wanda and Tadeusz – with their dog, Mirelka, and also a divorcee, Małgorzata, accompanied by her much younger partner, Jan , and her mother. The sea, drinks, and nude sunbathers make the family members on both sides more open and ready to shed their masks.
