Milan leaves his home and joins the "youth brigade", a group of young people who worked on a railway track. Tragedy strikes when Milan is injured operating one of the mechanical drills that make the building of tunnels possible. But his dedication is greater than his pain, and so he rushes back to the building site instead of staying in the hospital so that he can help the brigade meet the deadline for the completion of the tunnel.
