A young engineer arrives in a small provincial town and falls in with a traffic police inspector, a driving instructor, and a cannery-engineering manager. From sheer boredom, the inspector tickets a driver who has not broken the regulations. The driving instructor takes advantage of his position to seduce one of his students. To kill time, the engineering manager spends his time intriguing. These passions seem to be all that the three of them live for.
