Sometimes, parents might feel like their child has been replaced … and two families with the same surname “Sidorenki” know this for sure: their sons were misplaced in the maternity clinic and the truth was revealed only 16 years later. The surname is the only thing that two families have in common, and they even pronounce it differently. The SidorEnko family lives in an old house with the toilet outside. The head of the family, Peter, cannot even hold out for two days at a new job, and his business ideas are more likely to harm the family budget than replenish it. For breakfast, lunch and dinner the SidorEnko family has dumplings without sour cream, and Roma’s son has to sleep in the same bed with his grandfather, since there is no more room in the house. Vova SidOrenko was much more fortunate: his dad is an influential businessman. He lives in an estate with two swimming pools, a cinema, a gym and a small zoo in the backyard. The SidOrenko family is wealthy, but very progressive – they drive an electric car, sort garbage, and every morning they start with yoga and sprouted wheat for breakfast. When two such different families gather in the same house, misunderstandings, conflicts and funny situations cannot be avoided.
