The outside world with its microbes and viruses is deadly for the boy Gosha. That's why he never left the hospital until the disappearance of Oni's only friend made him forget about the danger. The boy goes on an amazing journey through New Year's Moscow, and Valera, a wayward courier, helps him in this, in many ways an even bigger child than Gosha himself. Together they face a path that will forever change not only their lives, but also make Moscow a little kinder.
