On a cold Moscow day in 1950, a woman gives birth after a hard and painful labor. But nature has prepared a surprise for her: although she’s expecting one baby, there turns out to be two. And as soon as the twins are born, word goes to a renowned scientist who – rather ominously – has been waiting for just this moment.
But while the babies each have their own heads and their own sets of lungs, something else soon becomes clear: the twins are joined together. And Maria and Daria Krivoshlyapova – also known as Masha and Dasha – will remain linked for the rest of their days. What’s more, even though it’s impossible to distinguish the identical girls at birth, the task will be a considerably easier one in the future.
