"The film illustrates the usefulness of the light alloy assault bridge. Soldiers unload the pieces of the bridge from a truck, assemble various modules until the span is complete. The spans are planed across a ravine - trucks and jeeps cross. A group of officers examine the bridge. The bridge is then partially dismantled and moved to a river. There, the bridge is floated on pontoons. Again, trucks, jeeps and tanks cross. Finally, pieces of the bridge are placed in a fire to show that they are not flammable."
