Description: Segment 1 Opening credits. The narrator introduces a brief historical reenactment of 1882, the year that Robert Koch discovered the germ that causes tuberculosis. A graph shows the decline in deaths since his discovery, yet the narrator points out that it still kills 23,000 people each year. The narrator introduces two sisters, Betty and Joan, who work in the same factory. Betty feels run down and her manager tells her to see a doctor. Joan goes with her and Betty is examined by the doctor. Joan has a cough so he sends them both for chest x-rays. The x-rays are shown. Betty is healthy but Joan has a patch of tuberculosis on her lungs. The doctor is shown speaking to Joan, and the narrator says that she will be shocked, but reassured that it was caught early. She goes to a sanatorium for treatment. An animation shows the treatment a needle collapses the diseased lung, allowing it to rest while the other lung works. The hospital staff are seen looking after the patients. The narrator explains that there are not enough nurses and beds to treat everyone, so some must have home care. A man is shown in bed at home being visited by the tuberculosis health visitor. He spends his time painting in bed. The sanatorium is seen again and Joan has recovered. An animation shows the diseased patch on her lung shrunk to a much smaller size. The narrator introduces the National Health Service's mass radiography programme. Mobile x-ray units visit towns and villages, and men and women are shown having chest x-rays. The film ends with an intertitle telling people to see a doctor if they suspect anything.
