Jancsi is part of a closely knit gang of young engineers. They see the older engineers as mediocre, and have grand ideas about developing new inventions together. With changing living conditions the five friends start to grow apart. At a party Jancsi suddenly meets Éva Halk. They fall in love, and find common memories in the engagement in The Pioneer Railway at the age of 12.
