'The Signal' is the story of two peasants who work as track walkers on the railway, Semyon Ivanov and Vasily Stepanych. Semyon is grateful for his job and the hut and the vegetable patch which goes with it, but Vasily is discontented with his lot and constantly complains, including to his employers. This grumbling irritates the railway officials, and eventually the situation escalates, driving Vasily to take terrible revenge on the state railway.
