Koistinen is a security guard at a shopping center whose dreams of a better life are continually crushed. Things seem to be looking up when Mirja shows an amorous interest in him but what he doesn't realize is that he's being set up as the fall guy by a gang of jewel thieves. Observing his plight is Aila, who runs a fast food stall and carries a torch for him but is overlooked in favor of Mirja.
