Dutch promotional film showing shots of cables being laid in a busy street. The film also shows the convenience that electricity brings to household chores, such as ironing and vacuuming. Many devices are filmed in close-up. In this film, Otto van Neijenhoff employs more of an avant-garde style than he typically does in his other films. Atmospheric images of trams and trains, with much use of dissolves, as well as evening and night shots in the illuminated city.
