The strict customs regulations have brought about a special type of lawbreaker - smugglers! They abound in all countries, and even in our relatively peaceful country, there are more of them than one would think. The great film director Stenbuk reads sensational articles about a major smuggling affair, and he sends a manuscript back to two writers with the message that if they do not come up with a smuggling-themed manuscript within eight days, they can run and chicken.

An American gangster nicknamed "English Joe" has fled across the Mexican border with his gang, consisting of four men in addition to himself. The American police are after them because of a bank robbery in which they killed several of the bank's employees. But "English Joe" soon comes up with a new plan that can bring them to safety for a while and at the same time give them the opportunity for a new coup. An old engineer who has worked at a weapons factory in Mexico has traveled home to his own country to complete an epoch-making invention: the silent machine gun. The men are ordered to Denmark, where the old engineer now lives.
