For 73 years now, the family has been waiting for news from the radio operator Pykhteev who went to the front. The last postcard from him came in 1945. Already the third generation is trying to find out the fate of the missing man. And all these years there is another family that knows nothing about the first one.

But a famous actor is not ready to recognize an uncle in a stranger. He requires a DNA test!
