Based on the novel by Natan Rybak “Soldiers Without Uniforms”. Director of a research institute engaged in research in the field of nuclear physics, Maxim Nerchin is testing a new research method. And although the method did not justify itself, Nerchin with unreasonable confidence began to build a more powerful installation... He uses almost all the institute's funds to create it and is so sure of success that he loudly announced it at a foreign symposium, thereby causing special attention to his institute on the part of those American circles who are primarily interested in creating weapons that bring death and destruction...

An idealistic, sophisticated young woman meets a rough-around-the-edges, blue collar man and rejects him, only to find out later that they are destined for true love together, despite the fact that he cannot now pass his certification test after she threw him out of her adult education class.
