They had a warm relationship in their family, until one day their only son Danila presents his new girlfriend Nyusha to his parents.

However for the happiness of their son, Lena and Pavel decide to close their eyes to the daughter-in-law's tricks, but this kindness turns into a real nightmare for them.
