Timofey Tkachev

May, 1945... A young pilot Aleksey Kaverin stationed in Germany is going home to Russia for vacation. The problem is he needs to bring a bride. And not only to himself but to four his friends as well.

One day Pavel, a young man wounded in the war, suddenly shows up at the home of a Moscow scientist name Krymov and claims to be his illegitimate son. Krymov denies this, but out of compassion he helps arrange a necessary operation for Pavel. Then certain things begin happening which suggest to Krymov that he may have a psychologically unstable fellow on his hands.
