White Mama (2018)

Аlina Makarova is a mother of six of her own children and one adopted child. Her ex husband is from Ethiopia, and all her own children are mixed race. Only her adopted son is white, but he has serious health problems and is psychologically unstable. Alina's older children realise what complications the adoption might bring and are afraid that there won't be enough room, time and love for everyone. But she convinces them that it's the right thing.
