Amsterdam in the 1950's. The story of the Dutch diamond trade and tuberculosis of the workforce in the 1950's.
A general view of Amsterdam, Netherlands, Europe, showing a large church or Cathedral by a wide canal. A street scene shows plant and flower stalls with a street vendor examining produce. Boats and barges are shown travelling on a canal while the narration comments on Amsterdam's importance as a port. A scene on a bridge over a canal shows a busker watched by three bystanders. These men are smoking, while they watch the street performer, who plays a guitar and a harmonica. We see the outside of a factory, while an open truck passes on the road. The narration sets Amsterdam as the greatest centre of the world's diamond industry.
Inside a factory a row of men sit at a long equipment filled work bench, inspecting diamonds. A close up of a worker shows him examining a large cut diamond with an eye-glass. He then displays it between his thumb and first finger and makes it sparkle. Long benches of equipment are shown in a light and spacious room. Two workers stand at these. A young man works at a grinding or polishing machine, which is then shown in close-up. A woman worker uses a grinding machine. The soundtrack comments on the poor working conditions in the industry fifty years before, and mentions the prevalence of tuberculosis or TB amongst diamond workers.

The narration tells us that the film is about the fight against T.B. undertaken by Jan van Zutphen, who became secretary of the diamond workers union just after the turn of the twentieth century. He is pictured in a factory shaking the hand of a worker at the time of the film's making, aged 89. He wears a suit, is bald, with a long white beard and has small round tortoise-shell spectacles. He walks behind a row of polishers watching them practice their trades. A close-up of a polisher
