The Karelin family is going to the dacha - the beautiful Zhenya, her teenage son Artem, her husband - the head of the family Vladimir, and her daughter - the golden-haired baby Agniya. The weekend, unfortunately, will be overshadowed by a painful necessity - Vladimir's father, suffering from dementia, lives in the country under the supervision of a nurse. This old man's dark past is bursting out and will cause trouble for anyone who happens to be nearby.
