Engineer Lobanov, Cand. Sc., is working on the design of a detector, a remote control instrument for locating damaged electrical cables. Wishing to be closer to the practical use of his instrument, he leaves his research institute for a production company, to start his activities with restructuring his Department, where Lebedev's new approach and creative plans find support. Yet, the trouble-making Assistant Head of the Department is out to obstruct the work on the detector. Lobanov's urgency and persistence, his team's support, and his confidence in the need for the detector lead the inventor to victory.
