Un gruppo di operai lavora alla tesatura d'una linea elettrica ad alta tensione. Il documentario, realizzato tra le montagne del Trentino, si propone di valorizzare le note umane di questo pericoloso lavoro, la curiosità e lo stupore dei valligiani di fronte alla novità. I tre grossi fili, allacciati alla centrale e tesi sugli alti tralicci, porteranno fino a Milano la corrente ottenuta dallo sfruttamento dei torrenti alpini.
