In this drama, a Soviet nuclear physicist and his professor are working in Siberia on a project when an accident leaves them exposed to incredible amounts of radiation. The professor dies, and the physicist is told that any more radiation will kill him. Still he persists on continuing the work. He becomes so obsessed with his work that he ignores his lover who is tempted by his friend. He does finally wake up and marry her. Meanwhile, the good friend teams up with him. Again an accident occurs and the determined physicist is exposed, but this time he swears his friend to secrecy until the experiment is over. Now he spends less and less time with his loving wife and she wonders what she has done wrong. It is nothing; he has gone to Moscow for a life-saving bone marrow transplant. The day before the operation, the friend bursts in with great news: the experiment was successful! Adding to the happy moment is his wife who anxiously awaits outside the operating room. Soon they receive a note from him that promises a great celebration.
