Summary: A professor is teaching high school students about tuberculosis. The school tests for the possibility of infection. Thirty per cent of the students have been exposed. X-rays indicate only one or two are actually infected. Film illustrates how the disease is contracted, pathology of the disease, and the Neumothorax operation. That operation collapses the lung so it can rest and recuperate, then it can be replenished with air.
