The post office building of a new housing development has almost been completed, but it will be a few weeks before it officially opens. In this crime caper comedy, a few schemers and con-artists wonder what would happen if they "opened" it a week early? A lot of money comes and goes by mail; they could make a killing. They decide to try to pull off this scheme, little suspecting that in the course of it, they will have to cope with a would-be bomber, a postal strike, and a blackmail attempt, as well as the police and the authorities.
