Two young workmen's teams are finishing a newly completed oil pipeline. A defect is discovered, which is blamed on one of the team members, Lado, and he is taken to the blacksmith shop. There is another socialist competition between the teams. A machine tool part suddenly goes missing from the first team, which will disrupt the entire work. The head of the second team is accused of stealing the part, but it soon turns out that he stole it from Lado in order to take revenge. At the general meeting, they demand Lado's dismissal, but the young worker's foreman intervenes and, at his request, Lado remains in the factory. The teams involved in the competition complete the plan ahead of schedule, their pictures are posted on the red board.
