Three sketches: O Importador de Ópio (the import trader of opium); Doca de Patane (Patane docks); Mayana (Mayana). Macau's crime squad raids some suspect places to stop the import and spreading of opium consumption in the Chinese territory of Macau under Portuguese administration. The people of Macau live an otherwise active and peaceful life: busy streets, love affairs, betting on the greyhound dogs' races, leisure meals on board of river boat restaurants, a European style marriage, a Chinese rite funeral, street peddling, and luscious sunsets.
