Lugosi works in the locomotive factory, earning little. He does not feel at ease in the world. One reason for his discontent is that his wife - a tractor factory worker - earns more than he does, and another is that she has even had her innovation accepted, while his has not. And because trouble doesn't come alone, poor Lugosi gets involved in a sabotage case.
