Panserbasse (1936)

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.
