Two strangers meet in an ambulance train during WWII.

For the first time, Natasha saw Elektron Yevdokimov at the Polytechnic Museum, where she came with Feliks. Then she really liked the confident speaker. Relations with Feliks didn't work out, and Natasha, leaving home, became a flight attendant — that is what she called her new profession. Once in a cafe, before the next flight, Natasha saw Yevdokimov. They met and began to meet. They experience their feelings for each other in different ways. By the power of her love, Natasha makes Yevdokimov understand what love is.
